Uridine phosphorylase is a pyrimidine-salvage enzyme that catalyzes the reversible phosphorolysis of uridine to uracil and alpha-D-ribose 1-phosphate. It participates in the pathways of pyrimidine ribonucleoside degradation and salvage, and the mammalian enzyme also accepts 2'-deoxyuridine. It occurs in viruses and cellular organisms.
