Using Graphs of Dynamic Hydrogen-Bond Networks To Dissect Conformational Coupling in a Protein Motor.
Karathanou, Journal of chemical information and modeling 2019 (PubMed)
- GeneRIF: Mutations near the nucleotide-binding site or changes of the nucleotide-binding state of SecA associate with altered dynamics at the preprotein binding domain and identify extended networks of hydrogen bonds that connect the active site of SecA to the region where SecA binds newly synthesized secretory proteins. Water molecules participate in hydrogen-bonded water chains that bridge functional domains of SecA.

function: Required for protein export, interacts with the SecYEG preprotein conducting channel. SecA has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving both as a receptor for the preprotein-SecB complex and as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane.
catalytic activity: ATP + H2O + cellular proteinSide 1 = ADP + phosphate + cellular proteinSide 2.
cofactor: Zn(2+) (Binds 1 zinc ion per subunit. Zinc is required for binding of the SecB chaperone to the extreme C-terminus of SecA.)
subunit: Monomer and homodimer; probably dimeric in the cytoplasm. It is not yet clear whether the form that functions in protein insertion is monomeric or dimeric. Part of the essential protein translocation apparatus which comprises SecA, SecYEG and auxiliary proteins SecDF- YajC and YidC. Makes direct contact with SecY
disruption phenotype: Essential. Leads to loss of translocation of lipoproteins Lpp and BRP.
substrates: proteins
tcdb comment: A biphasic pulling force may act on TMSs during translocon-mediated membrane integration (Ismail et al. 2012). Intermediate structures for the insertion of integral membrane proteins have been visualized (Bischoff et al. 2014). Insertion of the Type II single span (N-terminus, in, C-terminus, out) protein, RodZ, requires only SecYEG, SecA and the pmf, but not SecB, SecDF, YidC or FtsY (Rawat et al. 2015). The combined effects of ribosome and peptide binding to SecYEG may allow for co-translational membrane insertion of successive transmembrane segments (Ge et al. 2014). SecA penetrates deeply into the SecYEG channel during insertion, contacting transmembrane helices and periplasmic loops (Banerjee et al. 2017)

function: Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving both as a receptor for the preprotein-SecB complex and as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane.
catalytic activity: ATP + H2O + cellular proteinSide 1 = ADP + phosphate + cellular proteinSide 2.
cofactor: Zn(2+) (Binds 1 zinc ion per subunit.)
subunit: Monomer and homodimer (By similarity). Part of the essential Sec protein translocation apparatus which comprises SecA, SecYEG and auxiliary proteins SecDF-YajC and YidC (By similarity). Forms a complex with SecB (PubMed:14517549).

SP_RS08710 accessory Sec system translocase SecA2 from Streptococcus pneumoniae TIGR4
SP_1759 preprotein translocase subunit SecA from Streptococcus pneumoniae TIGR4
39% identity, 95% coverage

function: Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane. Plays a role in export of a number of proteins from the cell including glycosylated PsrP and pneumolysin (ply) (PubMed:28456649).
catalytic activity: ATP + H2O + cellular proteinSide 1 = ADP + phosphate + cellular proteinSide 2.
subunit: Monomer and homodimer. Part of the essential Sec protein translocation apparatus which comprises SecA, SecYEG and auxiliary proteins SecDF. Other proteins may also be involved.
disruption phenotype: A single gene deletion has about 60% decreased biofilm formation, 75% decreased adherence to human lung pneumocytes. Has higher pneumolysin (ply) i.e. hemolytic activity in the cytoplasm but less in the cell wall. Decreased levels of a number of cell wall and secreted proteins (PubMed:28456649). Deletion of 15 genes (from psrP, SP_1772 to SP_1756, includes the accessory Sec export proteins SecA2 and SecY2) and infection of female BALB/cJ mice, shows the psrP- secY2A2 region is required for lung infection and for infection to progress to blood. Mice infected intraperitoneally showed wild-type infection. Decreased adherence to lung but not pharynx or brain cells. The psrP-secY2A2 region deletion has no effect on bacterial growth rate, capsule levels, autolysis, or transformation (PubMed:18507531). In vitro significantly decreased biofilm formation is seen; the large deletion mutant (SP_1772 to SP_1756) is no more affected than the single psrP deletion (PubMed:20714350).

TC 3.A.5.10.1 / Q9AET6 SecA2, component of The GspB-specific secretory system (accessory Sec system for export of the 286 kDa cell wall-anchored platelet-binding adhesin, GspB) (Bensing and Sullam, 2002; Bensing et al., 2004; Takamatsu et al., 2004, 2005). These extra Sec systems are found in species of Streptococcus, Mycobacterium, and Listeria (Rigel and Braunstein, 2008). A region of approximately 20 residues from the amino-terminal end of mature GspB (the accessory Sec transport or AST domain) is essential, possibly as an α-helix, for SecA2/Y2-dependent transport. This AST domain may be essential, both for targeting to the SecA2/Y2 translocase, and for initiating translocation through the SecY2 channel from Streptococcus gordonii (see 4 papers)

Statistics

The PaperBLAST database links 793,807 different protein sequences to 1,259,118 scientific articles. Searches against EuropePMC were last performed on March 13 2025.

How It Works

PaperBLAST builds a database of protein sequences that are linked to scientific articles. These links come from automated text searches against the articles in EuropePMC and from manually-curated information from GeneRIF, UniProtKB/Swiss-Prot, BRENDA, CAZy (as made available by dbCAN), BioLiP, CharProtDB, MetaCyc, EcoCyc, TCDB, REBASE, the Fitness Browser, and a subset of the European Nucleotide Archive with the /experiment tag. Given this database and a protein sequence query, PaperBLAST uses protein-protein BLAST to find similar sequences with E < 0.001.

To build the database, we query EuropePMC with locus tags, with RefSeq protein identifiers, and with UniProt accessions. We obtain the locus tags from RefSeq or from MicrobesOnline. We use queries of the form "locus_tag AND genus_name" to try to ensure that the paper is actually discussing that gene. Because EuropePMC indexes most recent biomedical papers, even if they are not open access, some of the links may be to papers that you cannot read or that our computers cannot read. We query each of these identifiers that appears in the open access part of EuropePMC, as well as every locus tag that appears in the 500 most-referenced genomes, so that a gene may appear in the PaperBLAST results even though none of the papers that mention it are open access. We also incorporate text-mined links from EuropePMC that link open access articles to UniProt or RefSeq identifiers. (This yields some additional links because EuropePMC uses different heuristics for their text mining than we do.)

For every article that mentions a locus tag, a RefSeq protein identifier, or a UniProt accession, we try to select one or two snippets of text that refer to the protein. If we cannot get access to the full text, we try to select a snippet from the abstract, but unfortunately, unique identifiers such as locus tags are rarely provided in abstracts.

PaperBLAST also incorporates manually-curated protein functions:

Proteins from NCBI's RefSeq are included if a GeneRIF entry links the gene to an article in PubMed^®. GeneRIF also provides a short summary of the article's claim about the protein, which is shown instead of a snippet.
Proteins from Swiss-Prot (the curated part of UniProt) are included if the curators identified experimental evidence for the protein's function (evidence code ECO:0000269). For these proteins, the fields of the Swiss-Prot entry that describe the protein's function are shown (with bold headings).
Proteins from BRENDA, a curated database of enzymes, are included if they are linked to a paper in PubMed and their full sequence is known.
Every protein from the non-redundant subset of BioLiP, a database of ligand-binding sites and catalytic residues in protein structures, is included. Since BioLiP itself does not include descriptions of the proteins, those are taken from the Protein Data Bank. Descriptions from PDB rely on the original submitter of the structure and cannot be updated by others, so they may be less reliable. (For SitesBLAST and Sites on a Tree, we use a larger subset of BioLiP so that every ligand is represented among a group of structures with similar sequences, but for PaperBLAST, we use the non-redundant set provided by BioLiP.)
Every protein from EcoCyc, a curated database of the proteins in Escherichia coli K-12, is included, regardless of whether they are characterized or not.
Proteins from the MetaCyc metabolic pathway database are included if they are linked to a paper in PubMed and their full sequence is known.
Proteins from the Transport Classification Database (TCDB) are included if they have known substrate(s), have reference(s), and are not described as uncharacterized or putative. (Some of the references are not visible on the PaperBLAST web site.)
Every protein from CharProtDB, a database of experimentally characterized protein annotations, is included.
Proteins from the CAZy database of carbohydrate-active enzymes are included if they are associated with an Enzyme Classification number. Even though CAZy does not provide links from individual protein sequences to papers, these should all be experimentally-characterized proteins.
Proteins from the REBASE database of restriction enzymes are included if they have known specificity.
Every protein with an evidence-based reannotation (based on mutant phenotypes) in the Fitness Browser is included.
Sequence-specific transcription factors (including sigma factors and DNA-binding response regulators) with experimentally-determined DNA binding sites from the PRODORIC database of gene regulation in prokaryotes.
Putative transcription factors from RegPrecise that have manually-curated predictions for their binding sites. These predictions are based on conserved putative regulatory sites across genomes that contain similar transcription factors, so PaperBLAST clusters the TFs at 70% identity and retains just one member of each cluster.
Coding sequence (CDS) features from the European Nucleotide Archive (ENA) are included if the /experiment tag is set (implying that there is experimental evidence for the annotation), the nucleotide entry links to paper(s) in PubMed, and the nucleotide entry is from the STD data class (implying that these are targeted annotated sequences, not from shotgun sequencing). Also, to filter out genes whose transcription or translation was detected, but whose function was not studied, nucleotide entries or papers with more than 25 such proteins are excluded. Descriptions from ENA rely on the original submitter of the sequence and cannot be updated by others, so they may be less reliable.

Except for GeneRIF and ENA, the curated entries include a short curated description of the protein's function. For entries from BioLiP, the protein's function may not be known beyond binding to the ligand. Many of these entries also link to articles in PubMed.

For more information see the PaperBLAST paper (mSystems 2017) or the code. You can download PaperBLAST's database here.

Changes to PaperBLAST since the paper was written:

November 2023: incorporated PRODORIC and RegPrecise. Many PRODORIC entries were not linked to a protein sequence (no UniProt identifier), so we added this information.
February 2023: BioLiP changed their download format. PaperBLAST now includes their non-redundant subset. SitesBLAST and Sites on a Tree use a larger non-redundant subset that ensures that every ligand is represented within each cluster. This should ensure that every binding site is represented.
June 2022: incorporated some coding sequences from ENA with the /experiment tag.
March 2022: incorporated BioLiP.
April 2020: incorporated TCDB.
April 2019: EuropePMC now returns table entries in their search results. This has expanded PaperBLAST's database, but most of the new entries are of low relevance, and the resulting snippets are often just lists of locus tags with annotations.
February 2018: the alignment page reports the conservation of the hit's functional sites (if available from from Swiss-Prot or UniProt)
January 2018: incorporated BRENDA.
December 2017: incorporated MetaCyc, CharProtDB, CAZy, REBASE, and the reannotations from the Fitness Browser.
September 2017: EuropePMC no longer returns some table entries in their search results. This has shrunk PaperBLAST's database, but has also reduced the number of low-relevance hits.

Many of these changes are described in Interactive tools for functional annotation of bacterial genomes.

Secrets

PaperBLAST cannot provide snippets for many of the papers that are published in non-open-access journals. This limitation applies even if the paper is marked as "free" on the publisher's web site and is available in PubmedCentral or EuropePMC. If a journal that you publish in is marked as "secret," please consider publishing elsewhere.

Omissions from the PaperBLAST Database

Many important articles are missing from PaperBLAST, either because the article's full text is not in EuropePMC (as for many older articles), or because the paper does not mention a protein identifier such as a locus tag, or because of PaperBLAST's heuristics. If you notice an article that characterizes a protein's function but is missing from PaperBLAST, please notify the curators at UniProt or add an entry to GeneRIF. Entries in either of these databases will eventually be incorporated into PaperBLAST. Note that to add an entry to UniProt, you will need to find the UniProt identifier for the protein. If the protein is not already in UniProt, you can ask them to create an entry. To add an entry to GeneRIF, you will need an NCBI Gene identifier, but unfortunately many prokaryotic proteins in RefSeq do not have corresponding Gene identifers.
