Function

UDP_SALTY 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).

Publication Abstract from PubMed

Uridine nucleoside phosphorylase is an important drug target for the development of anti-infective and antitumour agents. The X-ray crystal structure of Salmonella typhimurium uridine nucleoside phosphorylase (StUPh) complexed with its inhibitor 2,2'-anhydrouridine, phosphate and potassium ions has been solved and refined at 1.86 A resolution (R(cryst) = 17.6%, R(free) = 20.6%). The complex of human uridine phosphorylase I (HUPhI) with 2,2'-anhydrouridine was modelled using a computational approach. The model allowed the identification of atomic groups in 2,2'-anhydrouridine that might improve the interaction of future inhibitors with StUPh and HUPhI.
