nucleoside phosphorylase-I family; The nucleoside phosphorylase-I family members accept a range of purine nucleosides as well as the pyrimidine nucleoside uridine. The NP-1 family includes phosphorolytic nucleosidases such as purine nucleoside phosphorylase (PNP, EC. 2.4.2.1), uridine phosphorylase (UP, EC 2.4.2.3), and 5'-deoxy-5'-methylthioadenosine phosphorylase (MTAP, EC 2.4.2.28), and hydrolytic nucleosidases such as AMP nucleosidase (AMN, EC 3.2.2.4) and 5'-methylthioadenosine/S-adenosylhomocysteine (MTA/SAH) nucleosidase (MTAN, EC 3.2.2.16). Members of this family display different physiologically relevant quaternary structures: hexameric (trimer-of-dimers arrangement of Shewanella oneidensis MR-1 UP); homotrimeric (human PNP and Escherichia coli PNPII or XapA); hexameric (with some evidence for co-existence of a trimeric form) such as E. coli PNPI (DeoD); or homodimeric such as human and Trypanosoma brucei UP. The NP-I family is distinct from nucleoside phosphorylase-II, which belongs to a different structural family.

10-168 7.18e-100

uridine phosphorylases similar to a human UPP1 and UPP2; Uridine phosphorylase (UP) catalyzes the reversible phosphorolysis of uracil ribosides and analogous compounds to their respective nucleobases and ribose 1-phosphate. Human UPP1 has a role in the activation of pyrimidine nucleoside analogues used in chemotherapy, such as 5-fluorouracil. This subfamily belongs to the nucleoside phosphorylase-I (NP-I) family, whose members accept a range of purine nucleosides as well as the pyrimidine nucleoside uridine. The NP-1 family includes phosphorolytic nucleosidases, such as purine nucleoside phosphorylase (PNPs, EC. 2.4.2.1), uridine phosphorylase (UP, EC 2.4.2.3), and 5'-deoxy-5'-methylthioadenosine phosphorylase (MTAP, EC 2.4.2.28), and hydrolytic nucleosidases, such as AMP nucleosidase (AMN, EC 3.2.2.4), and 5'-methylthioadenosine/S-adenosylhomocysteine (MTA/SAH) nucleosidase (MTAN, EC 3.2.2.16).

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. This subfamily belongs to the nucleoside phosphorylase-I (NP-I) family, whose members accept a range of purine nucleosides as well as the pyrimidine nucleoside uridine. The NP-1 family includes phosphorolytic nucleosidases, such as purine nucleoside phosphorylase (PNPs, EC. 2.4.2.1), uridine phosphorylase (UP, EC 2.4.2.3), and 5'-deoxy-5'-methylthioadenosine phosphorylase (MTAP, EC 2.4.2.28), and hydrolytic nucleosidases, such as AMP nucleosidase (AMN, EC 3.2.2.4), and 5'-methylthioadenosine/S-adenosylhomocysteine (MTA/SAH) nucleosidase (MTAN, EC 3.2.2.16). The NP-I family is distinct from nucleoside phosphorylase-II, which belongs to a different structural family.
