Candidate for 4 steps in catabolism of small carbon sources
| Pathway | Step | Score | Similar to | Id. | Cov. | Bits | Other hit | Other id. | Other bits |
|---|
| L-histidine catabolism | bgtA | med | BgtA aka SLR1735, component of Arginine/lysine/histidine/glutamine porter (characterized) | 53% | 97% | 248.1 | TcyC (YckI), component of Uptake system for L-cystine | 53% | 255.4 |
| L-asparagine catabolism | glnQ | med | 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) | 55% | 97% | 246.5 | TcyC (YckI), component of Uptake system for L-cystine | 53% | 255.4 |
| L-histidine catabolism | hisP | med | 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 (characterized) | 51% | 98% | 243.4 | TcyC (YckI), component of Uptake system for L-cystine | 53% | 255.4 |
| L-tryptophan catabolism | ecfA2 | lo | Energy-coupling factor transporter ATP-binding protein EcfA2; Short=ECF transporter A component EcfA2; EC 7.-.-.- (characterized, see rationale) | 39% | 77% | 140.2 | TcyC (YckI), component of Uptake system for L-cystine | 53% | 255.4 |

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 (a fast alternative to protein BLAST)
against a database of manually-curated proteins (most of which are experimentally characterized) or by using
HMMer with enzyme models (usually from
TIGRFam). Ublast hits may be split across two different proteins.
A candidate for a step is "high confidence" if either:
- ublast finds a hit to a characterized protein at above 40% identity and 80% coverage, and bits >= other bits+10.
- (Hits to curated proteins without experimental data as to their function are never considered high confidence.)
- HMMer finds a hit with 80% coverage of the model, and either other identity < 40 or other coverage < 0.75.
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:
- ublast finds a hit at above 40% identity and 70% coverage (ignoring otherBits).
- ublast finds a hit at above 30% identity and 80% coverage, and bits >= other bits.
- HMMer finds a hit (regardless of coverage or other bits).
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.
For diverse bacteria and archaea that can utilize a carbon source, there is a complete
high-confidence catabolic pathway (including a transporter) just 38% of the time, and
there is a complete medium-confidence pathway 63% of the time.
Gaps may be due to:
- our ignorance of proteins' functions,
- omissions in the gene models,
- frame-shift errors in the genome sequence, or
- the organism lacks the pathway.
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).
