IUBMB 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). N4'-Substituted pyridoxamine derivatives are also oxidized in reaction (1) to form pyridoxal 5'-phosphate and the corresponding primary amine.

The expected taxonomic range for this enzyme is: Bacteria, Eukaryota, Archaea
