EC	3.1.3.69
Accepted name:	glucosylglycerol 3-phosphatase
Reaction:	2-O-(α-D-glucosyl)-sn-glycerol-3-phosphate + H2O = 2-O-(α-D-glucopyranosyl)glycerol + phosphate
Other name(s):	salt tolerance protein A; StpA; 2-(β-D-glucosyl)-sn-glycerol-3-phosphate phosphohydrolase (incorrect)
Systematic name:	2-O-(α-D-glucopyranosyl)-sn-glycerol-3-phosphate phosphohydrolase
Comments:	Acts with EC 2.4.1.213 (glucosylglycerol-phosphate synthase) to form glucosylglycerol, an osmolyte that endows cyanobacteria with resistance to salt.
