Annotation score:3 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

This protein is involved in step 2 of the subpathway that synthesizes biotin from 7,8-diaminononanoate.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. ATP-dependent dethiobiotin synthetase BioD (bioD)
  2. Biotin synthase (bioB)
This subpathway is part of the pathway biotin biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes biotin from 7,8-diaminononanoate, the pathway biotin biosynthesis and in Cofactor biosynthesis.
