Reaction: 2-O-(α-D-glucopyranosyl)-D-glycerate + H2O = D-glucopyranose + D-glycerate
Other name(s): GG hydrolase; GgH
Systematic name: 2-O-(α-D-glucopyranosyl)-D-glycerate D-glucohydrolase
Comments: The enzyme has been isolated from nontuberculous mycobacteria (e.g. Mycobacterium hassiacum), which accumulate 2-O-(α-D-glucopyranosyl)-D-glycerate during growth under nitrogen deprivation.
