The Jann_0254 gene encodes the YP_508196.1 amino acid sequence that folds into a 174 residues long polypeptide containing a Pyridoxamine 5'-phosphate Oxidase like domain (PNPOx) between residues 30 to 100. This class of enzymes (PF01243) catalyzes the conversion of pyridoxamine-5-phosphate to pyridoxal-5-phosphate using flavin mono-nucleotide (FMN) as cofactor. This dimeric crystal structure, 2os5, presents 2 FMN molecules, each interacting with three regions of the protein around residues: R44-T45-V47; H61-T62-K68; Q90-R92. Based on the genome context where the gene codifying this protein is located, a predicted functional partner is YP_508198.
SCOP classifies 2os5 as an all beta structure in the superfamily FMN-binding split barrel, family PNPOx-like. Structural comparison searches provide the PNPOx-like structures PDB:1ci0, PDB:1t9m, PDB:1dnl as the most similar (Dali Z=15).
