EC 3.2.1.170

Accepted name: mannosylglycerate hydrolase

Reaction: 2-O-(6-phospho-α-D-mannosyl)-D-glycerate + H2O = D-mannose 6-phosphate + D-glycerate

Other name(s): 2-O-(6-phospho-mannosyl)-D-glycerate hydrolase; α-mannosidase (ambiguous); mngB (gene name)

Systematic name: 2-O-(6-phospho-α-D-mannosyl)-D-glycerate acylhydrolase

Comments: The enzyme participates in the mannosylglycerate degradation pathway of some bacteria. Mannosylglycerate is phosphorylated during transport into the cell, and the phosphorylated form is hydrolysed by this enzyme.
