[[http://www.uniprot.org/uniprot/UDP_SALTY 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 phosphorylase (UPh), which is a key enzyme in the reutilization pathway of pyrimidine nucleoside metabolism, is a validated target for the treatment of infectious diseases and cancer. A detailed analysis of the interactions of UPh with the therapeutic ligand 5-fluorouracil (5-FUra) is important for the rational design of pharmacological inhibitors of these enzymes in prokaryotes and eukaryotes. Expanding on the preliminary analysis of the spatial organization of the active centre of UPh from the pathogenic bacterium Salmonella typhimurium (StUPh) in complex with 5-FUra [Lashkov et al. (2009), Acta Cryst. F65, 601-603], the X-ray structure of the StUPh-5-FUra complex was analysed at atomic resolution and an in silico model of the complex formed by the drug with UPh from Vibrio cholerae (VchUPh) was generated. These results should be considered in the design of selective inhibitors of UPhs from various species.
