Comment |
The enzyme is found in diverse organisms including animals, plants, fungi, and bacteria. It hydrolyses triglycerides into diglycerides and subsequently into monoglycerides and free fatty acids. The enzyme is highly soluble in water and acts at the surface of oil droplets. Access to the active site is controlled by the opening of a lid, which, when closed, hides the hydrophobic surface that surrounds the active site. The lid opens when the enzyme contacts an oil-water interface (interfacial activation). The pancreatic enzyme requires a protein cofactor, namely colipase, to counteract the inhibitory effects of bile salts.
