3-phosphoglycerate Phosphatase

In enzymology, a 3-phosphoglycerate phosphatase (EC 3.1.3.38) is an enzyme that catalyzes the chemical reaction

D-glycerate 3-phosphate + H₂O D-glycerate + phosphate

Thus, the two substrates of this enzyme are D-glycerate 3-phosphate and H₂O, whereas its two products are D-glycerate and phosphate.

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is D-glycerate-3-phosphate phosphohydrolase. Other names in common use include D-3-Phosphoglycerate phosphatase, and 3-PGA phosphatase. This enzyme participates in glycine, serine and threonine metabolism.
