Function
GGP_BACIE Catalyzes both the (1) reversible phosphorolysis of 2-O-alpha-D-glucopyranosyl-sn-glycerol (GG) from beta-D-glucose 1-phosphate (betaGlc1P) and glycerol and (2) the hydrolysis of betaGlc1P. the betaGlc1P hydrolysis is a glucosyl-transfer reaction to an acceptor water molecule that produces an anomer-inverted alpha-glucose, not a phosphatase-type reaction. In the absence of glycerol produces alpha-D-glucopyranose and phosphate from beta-D-glucopyranose 1-phosphate.[1] [2]
