GapMind for catabolism of small carbon sources

 

sucrose catabolism in Dialister succinatiphilus YIT 11850

Best path

sut, SUS, scrK, galU, pgmA

Rules

Overview: Sucrose utilization in GapMind is based on MetaCyc pathways sucrose degradation I via sucrose 6-phosphate hydrolase (link), pathway II via sucrose synthase (link), pathway III via invertase (link), and pathway IV via sucrose phosphorylase (link). Pathway V is similar to pathway III and is not reported in prokaryotes, so it is not included. There is no pathway VI. Pathway VII (via sucrose 3-dehydrogenase, link) is too poorly understood to include in GapMind.

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).
