In enzymology, a 4-pyridoxolactonase (EC 3.1.1.27) is an enzyme that catalyzes the chemical reaction
- 4-pyridoxolactone + H2O 4-pyridoxate
Thus, the two substrates of this enzyme are and H2O, whereas its product is .
This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is 4-pyridoxolactone lactonohydrolase. This enzyme participates in vitamin B6 metabolism.
