Mannosyl-3-phosphoglycerate phosphatase

In enzymology, a mannosyl-3-phosphoglycerate phosphatase (EC 3.1.3.70) is an enzyme that catalyzes the chemical reaction

2(alpha-D-mannosyl)-3-phosphoglycerate + H2O 2(alpha-D-mannosyl)-D-glycerate + phosphate

Thus, the two substrates of this enzyme are 2(alpha-D-mannosyl)-3-phosphoglycerate and H2O, whereas its two products are 2(alpha-D-mannosyl)-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 alpha-D-mannosyl-3-phosphoglycerate phosphohydrolase.

Structural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1WZC and 1XVI.
