Common conditions

... then these annotations are applied i

Protein namei

  • Recommended name:
    Uridine phosphorylase (EC:2.4.2.3)

Functioni

  • 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.

Pathwayi

  • Pathwayi: UMP biosynthesis via salvage pathway

    This protein is involved in step 1 of the subpathway that synthesizes uracil from uridine (phosphorylase route). This subpathway is part of the pathway UMP biosynthesis via salvage pathway, which is itself part of Pyrimidine metabolism.

Sequence similaritiesi

Catalytic activityi

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