General annotation (Comments)

Function

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. HAMAP MF_01208

Catalytic activity

Orotidine 5'-phosphate + diphosphate = orotate + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP MF_01208

Cofactor

Magnesium By similarity. HAMAP MF_01208

Pathway

Pyrimidine metabolism; UMP biosynthesis via de novo pathway; UMP from orotate: step 1/2. HAMAP MF_01208

Subunit structure

Homodimer By similarity. HAMAP MF_01208

Sequence similarities

Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrE subfamily.
