Protein

Orotate phosphoribosyltransferase 1

Gene

URA5

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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

Miscellaneous

There are two genes coding for OPRT in yeast.
Present with 39300 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

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

Pathwayi: UMP biosynthesis via de novo pathway

This protein is involved in step 1 of the subpathway that synthesizes UMP from orotate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Orotate phosphoribosyltransferase 1 (URA5), Orotate phosphoribosyltransferase 2 (URA10)
  2. Orotidine 5'-phosphate decarboxylase (URA3)
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.
