A PF10590 PNPOx_C Pyridoxine 5'-phosphate oxidase C-terminal dimerisation region Domain Pyridoxine 5'-phosphate oxidase (PNPOx) catalyses the terminal step in the biosynthesis of pyridoxal 5'-phosphate (PLP), a cofactor used by many enzymes involved in amino acid metabolism. The enzyme oxidises either the 4'-hydroxyl group of pyridoxine 5'-phosphate (PNP) or the 4'-primary amine of pyridoxamine 5'-phosphate (PMP) to an aldehyde. PNPOx is a homodimeric enzyme with one flavin mononucleotide (FMN) molecule non-covalently bound to each subunit. This domain represents one of the two dimerisation regions of the protein, located at the edge of the dimer interface, at the C-terminus, being the last three beta strands, S6, S7, and S8 along with the last three residues to the end. In Swiss:P21159, S6 runs from residues 178-192, S7 from 200-206 and S8 from 211-215. the extended loop, of residues 167-177 may well be involved in the pocket formed between the two dimers that positions the FMN molecule [2].
