Protein

Orotate phosphoribosyltransferase

Gene

pyrE

Organism
Bacillus weihenstephanensis (strain KBAB4)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the transfer of a ribosyl phosphate group from 5-phosphoribose 1-diphosphate to orotate, leading to the formation of orotidine monophosphate (OMP).UniRule annotation

Catalytic activityi

Orotidine 5'-phosphate + diphosphate = orotate + 5-phospho-alpha-D-ribose 1-diphosphate.UniRule annotation

Cofactori

Mg2+UniRule annotation

Pathwayi: UMP biosynthesis via de novo pathway

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.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes UMP from orotate, the pathway UMP biosynthesis via de novo pathway and in Pyrimidine metabolism.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
