Description

Triglyceride lipases (EC:3.1.1.3) are lipolytic enzymes that hydrolyse ester linkages of triglycerides [PMID: 3147715]. Lipases are widely distributed in animals, plants and prokaryotes. At least three tissue-specific isozymes exist in higher vertebrates, pancreatic, hepatic and gastric/lingual. These lipases are closely related to each other and to lipoprotein lipase (EC:3.1.1.34), which hydrolyses triglycerides of chylomicrons and very low density lipoproteins (VLDL) [PMID: 2917565].

The most conserved region in all these proteins is centred around a serine residue which has been shown [PMID: 2304545] to participate, with an histidine and an aspartic acid residue, in a charge relay system. Such a region is also present in lipases of prokaryotic origin and in lecithin-cholesterol acyltransferase (EC:2.3.1.43) (LCAT) [PMID: 3458198], which catalyses fatty acid transfer between phosphatidylcholine and cholesterol.
