FUNCTION: Catalyzes the phosphorylation of the dietary vitamin B6 vitamers pyridoxal (PL), pyridoxine (PN) and pyridoxamine (PM) to form pyridoxal 5'-phosphate (PLP), pyridoxine 5'-phosphate (PNP) and pyridoxamine 5'-phosphate (PMP), respectively (PubMed:9099727, PubMed:10987144, PubMed:17766369, Pu...

PLP is the active form of vitamin B6, and acts as a cofactor for over 140 different enzymatic reactions. {ECO:0000269|PubMed:10987144, ECO:0000269|PubMed:17766369, ECO:0000269|PubMed:19351586, ECO:0000269|PubMed:31187503, ECO:0000269|PubMed:9099727, ECO:0000305}.
