Pyridoxal phosphatase

The enzyme pyridoxal phosphatase  (EC 3.1.3.74) catalyzes the reaction


 * pyridoxal 5′-phosphate + H2O $$\rightleftharpoons$$ pyridoxal + phosphate

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name is pyridoxal-5′-phosphate phosphohydrolase. Other names in common use include vitamine B6 (pyridoxine) phosphatase, PLP phosphatase, vitamin B6-phosphate phosphatase, and PNP phosphatase. This enzyme participates in vitamin B6 metabolism.
