RC STRAIN=ATCC BAA-149 / DSM 14245 / SRS30216; RG US DOE Joint Genome Institute; RA Copeland A., Lucas S., Lapidus A., Barry K., Glavina del Rio T., RA Hammon N., Israni S., Dalin E., Tice H., Pitluck S., Saunders E., RA Brettin T., Bruce D., Detter J.C., Han C., Schmutz J., Larimer F., RA Land M., Hauser L., Kyrpides N., Lykidis A., Bagwell C.E., RA Shimkets L., Berry C.J., Fliermans C., Richardson P.; RT "Complete sequence of chromosome of Kineococcus radiotolerans RT SRS30216."; RL Submitted (JUL-2007) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Catalyzes the oxidation of either pyridoxine 5'- CC phosphate (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal CC 5'-phosphate (PLP) (By similarity). CC -!- CATALYTIC ACTIVITY: Pyridoxamine 5'-phosphate + H(2)O + O(2) = CC pyridoxal 5'-phosphate + NH(3) + H(2)O(2). CC -!- CATALYTIC ACTIVITY: Pyridoxine 5'-phosphate + O(2) = pyridoxal 5'- CC phosphate + H(2)O(2). CC -!- COFACTOR: Binds 1 FMN per subunit (By similarity). CC -!- PATHWAY: Cofactor biosynthesis; B6 vitamer interconversion; CC pyridoxal 5'-phosphate from pyridoxamine 5'-phosphate: step 1/1. CC -!- PATHWAY: Cofactor biosynthesis; B6 vitamer interconversion; CC pyridoxal 5'-phosphate from pyridoxine 5'-phosphate: step 1/1. CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SIMILARITY: Belongs to the pyridoxamine 5'-phosphate oxidase CC family.
