Pathwayi: urea degradation

This protein is involved in step 1 of the subpathway that synthesizes CO(2) and NH(3) from urea (urease route).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Urease subunit beta (ureB), Urease subunit gamma (ureA), Urease subunit alpha (ureC)
This subpathway is part of the pathway urea degradation, which is itself part of Nitrogen metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes CO(2) and NH(3) from urea (urease route), the pathway urea degradation and in Nitrogen metabolism.
