additional information | pyridoxal kinase catalyzes the forward reactions with pyridoxal, pyridoxamine, and pyridoxine, while pyridoxal phosphotase (PL phosphatase, PDXP, EC 3.1.3.74) catalyzes the reverse reaction of dephophorylation | Homo sapiens | ? | - |

physiological function | vitamin B6 enters the cells after hydrolysis of the phosphorylated forms by the membrane-bound tissue non-specific alkaline phosphatase (TNSALP, EC 3.1.3.1). Once inside the cells, pyridoxal kinase (PL kinase, PDXK, EC 2.7.1.35) phosphorylates the hydroxymethyl group of PL, PN and PM to their respective 5'-phosphate forms | Homo sapiens |
