uridine phosphorylase; This model represents a clade of mainly eucaryotic uridine phosphorylases. Genes from human and mouse have been characterized. This enzyme is a member of the PHP/UDP subfamily (pfam01048) and is closely related to the bacterial uridine (TIGR01718) and inosine (TIGR00107) phosphorylase equivalogs. In addition to the eukaryotes, a gene from Mycobacterium leprae is included in this equivalog and may have resulted from lateral gene transfer.

uridine phosphorylases similar to Escherichia coli Udp and related phosphorylases; Uridine phosphorylase (UP) is specific for pyrimidines, and is involved in pyrimidine salvage and in the maintenance of uridine homeostasis. In addition to E. coli Udp, this subfamily includes Shewanella oneidensis MR-1 UP and Plasmodium falciparum purine nucleoside phosphorylase (PfPNP). PfPNP is an outlier in terms of genetic distance from the other families of PNPs. PfPNP is catalytically active for inosine and guanosine, and in addition, has a weak UP activity.

nucleoside phosphorylases similar to Toxoplasma gondii uridine phosphorylase; This subfamily is composed of mostly uncharacterized proteins with similarity to Toxoplasma gondii uridine phosphorylase (TgUPase). Toxoplasma gondii appears to have a single non-specific uridine phosphorylase which catalyzes the reversible phosphorolysis of uridine, deoxyuridine and thymidine, rather than the two distinct enzymes of mammalian cells: uridine phosphorylase (nucleoside phosphorylase-I family) and thymidine phosphorylase (nucleoside phosphorylase-II family).
