beta-diglucosyldiacylglycerol synthase and similar proteins. beta-diglucosyldiacylglycerol synthase (processive diacylglycerol beta-glucosyltransferase EC 2.4.1.315) is involved in the biosynthesis of both the bilayer- and non-bilayer-forming membrane glucolipids. This family of glycosyltransferases also contains plant major galactolipid synthase (chloroplastic monogalactosyldiacylglycerol synthase 1 EC 2.4.1.46). Glycosyltransferases catalyze the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds. The acceptor molecule can be a lipid, a protein, a heterocyclic compound, or another carbohydrate residue. The structures of the formed glycoconjugates are extremely diverse, reflecting a wide range of biological functions. The members of this family share a common GTB topology, one of the two protein topologies observed for nucleotide-sugar-dependent glycosyltransferases. GTB proteins have distinct N- and C- terminal domains each containing a typical Rossmann fold. The two domains have high structural homology despite minimal sequence homology. The large cleft that separates the two domains includes the catalytic center and permits a high degree of flexibility.

lipid kinase, YegS/Rv2252/BmrU family. The E. coli member of this family, YegS has been purified and shown to have phosphatidylglycerol kinase activity. The member from M. tuberculosis, Rv2252, has diacylglycerol kinase activity. BmrU from B. subtilis is in an operon with multidrug efflux transporter Bmr, but is uncharacterized.
