Rules

Overview: Phenylalanine utilization in GapMind is based on MetaCyc pathway L-phenylalanine degradation I (aerobic, via tyrosine, link), pathway II (anaerobic, via phenylacetaldehyde dehydrogenase, link), degradation via phenylpyruvate:ferredoxin oxidoreductase (PMC3346364), or degradation via phenylacetaldehyde:ferredoxin oxidoreductase (PMID:24214948). (MetaCyc describes additional pathways, but they do not result in carbon incorporation or are not reported in prokaryotes, so they are not included 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 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).

For more information, see the paper from 2019 on GapMind for amino acid biosynthesis, or view the source code.
