EC Number 1.4.3.5
CAS Registry Number 9029-21-4
Comments A flavoprotein (FMN). In Escherichia coli, the coenzyme pyridoxal 5′-phosphate is synthesized de novo by a pathway that involves EC 1.2.1.72 (erythrose-4-phosphate dehydrogenase), EC 1.1.1.290 (4-phosphoerythronate dehydrogenase), EC 2.6.1.52 (phosphoserine transaminase), EC 1.1.1.262 (4-hydroxythreonine-4-phosphate dehydrogenase), EC 2.6.99.2 (pyridoxine 5′-phosphate synthase) and EC 1.4.3.5 (with pyridoxine 5′-phosphate as substrate).
Cofactor FMN
History
Reactions (1) Pyridoxamine 5′-phosphate + H(2)O + O(2) = pyridoxal 5′-phosphate + NH(3) + H(2)O(2). (2) Pyridoxine 5′-phosphate + O(2) = pyridoxal 5′-phosphate + H(2)O(2).
