In enzymology, a galactolipid galactosyltransferase (EC 2.4.1.184) is an enzyme that catalyzes the chemical reaction

2 3-(beta-D-galactosyl)-1,2-diacyl-sn-glycerol 3-[alpha-D-galactosyl-(1->6)-beta-D-galactosyl]-1,2-diacyl-sn- glycerol + 1,2-diacyl-sn-glycerol

Hence, this enzyme has one substrate, 3-(beta-D-galactosyl)-1,2-diacyl-sn-glycerol, but 3 products: [[3-[alpha-D-galactosyl-(1->6)-beta-D-galactosyl]-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-(beta-D-galactosyl)-1,2-diacyl-sn-glycerol:mono-3-(beta-D-galactos yl)-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 (ambiguous), and digalactosyldiacylglycerol synthase (ambiguous). This enzyme participates in glycerolipid metabolism.

Chloroplasts contain several important membranes, vital for their function. Like mitochondria, chloroplasts have a double-membrane envelope, called the chloroplast envelope, but unlike mitochondria, chloroplasts also have internal membrane structures called thylakoids. Furthermore, one or two additional membranes may enclose chloroplasts in organisms that underwent secondary endosymbiosis, such as the euglenids and chlorarachniophytes.
