WebPhospholipases C are characterized by the site at which phospholipids are cleaved. Phospholipases have been isolated from both Gram-positive and Gram-negative bacteria, and all of these enzymes have been identified as a single polypeptide chain. WebPhospholipase C cleaves a. plasma membrane phospholipid. called PIP 2 into DAG and IP 3. A signal molecule binds. to a receptor, leading to. activation of phospholipase C. EXTRA-CELLULAR. FLUID. Signal molecule (first messenger) G protein. G-protein-linked. receptor. Various. proteins. activated. Endoplasmic. reticulum (ER) Phospholipase C.
