Phosphatidylinositol consists of a family of lipids made of a phosphate group, two fatty acid chains, and one inositol molecule. They represent a class of the phosphatidylglycerides. Typically phosphatidylinositols form a minor component on the cytosolic side of eukaryotic cell membranes. The phosphate group gives the molecules a negative charge at physiological pH.
Phosphoinositide phospholipase C is a family of eukaryotic intracellular enzymes that play an important role in signal transduction processes. These enzymes belong to a larger superfamily of Phospholipase C. Other families of phospholipase C enzymes have been identified in bacteria and trypanosomes. Phospholipases C are phosphodiesterases.
The enzyme phosphatidylinositol diacylglycerol-lyase catalyzes the following reaction:
The enzyme inositol-1,4-bisphosphate 1-phosphatase (EC 3.1.3.57) catalyzes the reaction
The enzyme phosphatidylinositol-3,4-bisphosphate 4-phosphatase (EC 3.1.3.66) that catalyzes the reaction
The enzyme phosphatidylinositol-3-phosphatase (EC 3.1.3.64) catalyzes the reaction
The enzyme phosphoinositide 5-phosphatase (EC 3.1.3.36) catalyzes the reaction
