GapMind for catabolism of small carbon sources

 

pyruvate catabolism in Ruegeria conchae TW15

Best path

yjcH, actP

Rules

Overview: Pyruvate is a central metabolite, so GapMind represents transport only.

13 steps (5 with candidates)

Or see definitions of steps

Step Description Best candidate 2nd candidate
yjcH putative small subunit of pyruvate transporter (yjcH-like) G7G_RS0105945
actP large subunit of pyruvate transporter (actP-like) G7G_RS0105940
Alternative steps:
btsT pyruvate symporter BtsT
cstA large subunit of pyruvate transporter (CstA)
dctM pyruvate TRAP transporter, large permease component G7G_RS0111790 G7G_RS0104905
dctP pyruvate TRAP transporter, substrate-binding component G7G_RS0114535
dctQ pyruvate TRAP transporter, small permease component
JEN1 pyruvate symporter JEN1
MCT4 pyruvate symporter MCT4 (SLC16A3)
mctC pyruvate symporter MctC G7G_RS0105940
mctP pyruvate permease MctP
SLC5A8 sodium-coupled pyruvate transporter
ybdD small subunit of pyruvate transporter (YbdD)

Confidence: high confidence medium confidence low confidence
transporter – transporters and PTS systems are shaded because predicting their specificity is particularly challenging.

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:

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. 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:

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).
