Candidate for 4 steps in catabolism of small carbon sources
| Pathway | Step | Score | Similar to | Id. | Cov. | Bits | Other hit | Other id. | Other bits |
|---|
| putrescine catabolism | potA | hi | PotG aka B0855, component of Putrescine porter (characterized) | 55% | 99% | 410.2 | Maltose-transporting ATPase (EC 3.6.3.19) | 42% | 260.8 |
| L-proline catabolism | opuBA | lo | BusAA, component of Uptake system for glycine-betaine (high affinity) and proline (low affinity) (OpuAA-OpuABC) or BusAA-ABC of Lactococcus lactis). BusAA, the ATPase subunit, has a C-terminal tandem cystathionine β-synthase (CBS) domain which is the cytoplasmic K+ sensor for osmotic stress (osmotic strength)while the BusABC subunit has the membrane and receptor domains fused to each other (Biemans-Oldehinkel et al., 2006; Mahmood et al., 2006; Gul et al. 2012). An N-terminal amphipathic α-helix of OpuA is necessary for high activity but is not critical for biogenesis or the ionic regulation of transport (characterized) | 35% | 87% | 188.7 | PotG aka B0855, component of Putrescine porter | 55% | 410.2 |
| L-histidine catabolism | hutV | lo | ABC transporter for L-Histidine, ATPase component (characterized) | 40% | 84% | 176.4 | PotG aka B0855, component of Putrescine porter | 55% | 410.2 |
| L-tryptophan catabolism | ecfA1 | lo | Energy-coupling factor transporter ATP-binding protein EcfA1; Short=ECF transporter A component EcfA; EC 7.-.-.- (characterized, see rationale) | 39% | 82% | 137.5 | PotG aka B0855, component of Putrescine porter | 55% | 410.2 |

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).
