Type: | Family | Name: | Triacylglycerol lipase family |
Description: | Triglyceride lipases () are lipolytic enzymes that hydrolyse ester linkages of triglycerides []. Lipases are widely distributed in animals, plants and prokaryotes. At least three tissue-specific isozymes exist in higher vertebrates, pancreatic, hepatic andgastric/lingual. These lipases are closely related to each other and to lipoprotein lipase (), which hydrolyses triglycerides of chylomicrons and very low density lipoproteins (VLDL) [].The most conserved region in all these proteins is centred around a serine residue which has been shown [] 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 () (LCAT) [], which catalyses fatty acid transfer between phosphatidylcholine and cholesterol. | Short Name: | TAG_lipase |
