CC -!- FUNCTION: B6-vitamer kinase involved in the salvage pathway of
CC pyridoxal 5'-phosphate (PLP). Catalyzes the phosphorylation of
CC pyridoxine (PN), pyridoxal (PL), and pyridoxamine (PM), forming their
CC respective 5'-phosphorylated esters, i.e. PNP, PLP and PMP.
CC {ECO:0000255|HAMAP-Rule:MF_01638}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + pyridoxal = ADP + H(+) + pyridoxal 5'-phosphate;
