Galactolipid galactosyltransferase
In enzymology, a galactolipid galactosyltransferase is an enzyme that catalyzes the chemical reaction
Hence, this enzyme has one substrate, 3--1,2-diacyl-sn-glycerol, but 3 products: 3--1,2-diacyl-sn-, glycerol, and 1,2-diacyl-sn-glycerol.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is 3--1,2-diacyl-sn-glycerol:mono-3--1,2-diacyl-sn-glycerol beta-D-galactosyltransferase. Other names in common use include galactolipid-galactolipid galactosyltransferase, galactolipid:galactolipid galactosyltransferase, interlipid galactosyltransferase, GGGT, DGDG synthase , and digalactosyldiacylglycerol synthase . This enzyme participates in glycerolipid metabolism.
