Glycerophosphocholine glycerophosphodiesterase responsible for the hydrolysis of intracellular glycerophosphocholine into glycerol-phosphate and choline (PubMed:16141200, PubMed:16172116). The choline is used for phosphatidyl-choline synthesis. Required for utilization of glycerophosphocholine as phosphate source (PubMed:16141200). May also use glycerophosphoinositol as substrate in vivo (PubMed:16172116). H2O + sn-glycerol 3-phosphocholine = choline + H(+) + sn-glycerol 3-phosphate H2O + sn-glycero-3-phospho-1D-myo-inositol = H(+) + myo-inositol + sn-glycerol 3-phosphate Affects the glycerophosphocholine metabolism but not the glycerophosphoinositol metabolism (PubMed:16141200). Present with 2300 molecules/cell in log phase SD medium. Belongs to the GDE1 family.
