Enzymes

General function:
Involved in protein binding
Specific function:
Glycerophosphocholine glycerophosphodiesterase responsible for the hydrolysis of intracellular glycerophosphocholine into glycerol-phosphate and choline. The choline is used for phosphatidyl-choline synthesis. Required for utilization of glycerophosphocholine as phosphate source
Gene Name:

Molecular weight:
138013.0
Reactions
A glycerophosphodiester + H(2)O → an alcohol + sn-glycerol 3-phosphate.
General function:
Involved in metabolic process
Specific function:
Sequentially removes both fatty acyl groups from diacylglycerophospholipids and therefore has both phospholipase A and lysophospholipase activities. Substrate preference is phosphatidylserine > phosphatidylinositol. Does not cleave phosphatidylcholine, phosphatidylethanolamine, phosphatidic acid and phosphatidylinositol-bisphosphate

Reactions
2-lysophosphatidylcholine + H(2)O → glycerophosphocholine + a carboxylate.
General function:
Involved in metabolic process
Specific function:
Intracellular phospholipase B that catalyzes the double deacylation of phosphatidylcholine (PC) to glycerophosphocholine (GroPCho). Plays an important role in membrane lipid homeostasis. Responsible for the rapid PC turnover in response to inositol, elevated temperatures, or when choline is present in the growth medium
