Dgat enzymes and triacylglycerol biosynthesis
Webof TAG catalyzed by DGAT is the final and unique step in TAG formation. It is believed that DGAT diverts 1,2-DAG from membrane phos-pholipid synthesis into TAG synthesis. Two mam-malian DGATs have been identified, DGAT 1 and 2 [13]. Both enzymes are membrane-associ-ated and share similar biochemical functions and tissue expression … WebThe diacylglycerol acyltransferases (DGAT) (diacylglycerol:acyl-CoA acyltransferase, EC 2.3.1.20) are a key group of enzymes that catalyse the final and usually the most important rate-limiting step of triacylglycerol biosynthesis in plants and other organisms. Genes encoding four distinct functiona …

WebJun 16, 2011 · Triacylglycerol (TG) is the major form of stored energy in eukaryotic organisms and is synthesized by two distinct acyl-CoA:diacylglycerol acyltransferase (DGAT) enzymes, DGAT1 and DGAT2. Both DGAT enzymes reside in the endoplasmic reticulum (ER), but DGAT2 also co-localizes with mitochondria and lipid droplets. WebFig. 1. Triacylglycerol synthesis and acyl-CoA:diacylglycerol acyl-transferase (DGAT) enzymes. A: Triacylglycerols (triglycerides) are the end-product of a multi-step pathway.
