This protein is involved in step 1 of the subpathway that synthesizes UMP from orotate.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Orotate phosphoribosyltransferase (pyrE)
  2. Orotidine 5'-phosphate decarboxylase (pyrF)
This subpathway is part of the pathway UMP biosynthesis via de novo pathway, which is itself part of Pyrimidine metabolism.
