Pyridoxal phosphatase
The enzyme pyridoxal phosphatase catalyzes the reaction
It also acts on pyridoxine phosphate, pyridoxamine phosphate, 4-pyridoxic acid phosphate and 4-deoxypyridoxine phosphate to remove their phosphate groups. Two human genes produce proteins that act as this kind of enzyme: PDXP and PHOSPHO2.
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 phosphatase, PLP phosphatase, vitamin B6-phosphate phosphatase, and PNP phosphatase. This enzyme participates in vitamin B6 metabolism.
