General annotation (Comments)

Function

Catalyzes the reversible phosphorylytic cleavage of uridine and deoxyuridine to uracil and ribose- or deoxyribose-1-phosphate. The produced molecules are then utilized as carbon and energy sources or in the rescue of pyrimidine bases for nucleotide synthesis By similarity.

Catalytic activity

Uridine + phosphate = uracil + alpha-D-ribose 1-phosphate.

Pathway

Pyrimidine metabolism; UMP biosynthesis via salvage pathway; uracil from uridine (phosphorylase route): step 1/1.

Subunit structure

Homohexamer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the PNP/UDP phosphorylase family.
