Finding step gltL for L-glutamate catabolism in Dinoroseobacter shibae DFL-12

5 candidates for gltL: L-glutamate ABC transporter, ATPase component (GltL/GluA/BztD/GlnQ/AatP/PEB1C)

Score Gene Description Similar to Id. Cov. Bits Other hit Other id. Other bits
hi Dshi_0321 ABC transporter related (RefSeq) BztD, component of Glutamate/glutamine/aspartate/asparagine porter (characterized) 84% 95% 427.9 ABC transporter for D-Alanine, ATPase component 75% 395.6
med Dshi_2221 ABC transporter related (RefSeq) Glutamine ABC transporter ATP-binding protein, component of Glutamine transporter, GlnQP. Takes up glutamine, asparagine and glutamate which compete for each other for binding both substrate and the transmembrane protein constituent of the system (Fulyani et al. 2015). Tandem substrate binding domains (SBDs) differ in substrate specificity and affinity, allowing cells to efficiently accumulate different amino acids via a single ABC transporter. Analysis revealed the roles of individual residues in determining the substrate affinity (characterized) 48% 98% 224.2 Probable ATP-binding component of ABC transporter, component of Amino acid transporter, PA5152-PA5155. Probably transports numerous amino acids including lysine, arginine, histidine, D-alanine and D-valine (Johnson et al. 2008). Regulated by ArgR 61% 296.6
med Dshi_1648 ABC transporter related (RefSeq) GluA aka CGL1950, component of Glutamate porter (characterized) 40% 98% 169.9 ABC transporter for D-Maltose and D-Trehalose, ATPase component 63% 431.8
med Dshi_2120 ABC transporter related (RefSeq) GluA aka CGL1950, component of Glutamate porter (characterized) 41% 98% 166 MalK aka PF1933, component of Maltooligosaccharide porter (Maltose is not a substrate, but maltotriose is.) 43% 250.8
med Dshi_2380 ABC transporter related (RefSeq) Glutamate/aspartate transport ATP-binding protein GltL aka B0652, component of Glutamate/aspartate porter (characterized) 41% 91% 151.4 Probable ribonucleotide transport ATP-binding protein mkl, component of The Mce/Yrb/Mlk (Mammalian cell entry) ABC-type putative steroid uptake transporter (involved in several aspects of mycobacterial pathogenesis) 42% 196.4

About GapMind

Each pathway is defined by a set of rules based on individual steps or genes. Candidates for each step are identified by using ublast against a database of manually-curated proteins (most of which are experimentally characterized) or by using HMMer. Ublast hits may be split across two different proteins.

A candidate for a step is "high confidence" if either:

where "other" refers to the best ublast hit to a sequence that is not annotated as performing this step (and is not "ignored").

Otherwise, a candidate is "medium confidence" if either:

Other blast hits with at least 50% coverage are "low confidence."

Steps with no high- or medium-confidence candidates may be considered "gaps." For the typical bacterium that can make all 20 amino acids, there are 1-2 gaps in amino acid biosynthesis pathways. Gaps may be due to:

GapMind relies on the predicted proteins in the genome and does not search the six-frame translation. In most cases, you can search the six-frame translation by clicking on links to Curated BLAST for each step definition (in the per-step page).
