Processive diacylglycerol glucosyltransferase; Is a processive glucosyltransferase involved in the synthesis of both bilayer- and non-bilayer-forming membrane glycolipids. Is able to successively transfer up to three glucosyl residues to diacylglycerol (DAG), thereby catalyzing the formation of mono-, di- and triglucosyldiacylglycerol. Diglucosyldiacylglycerol (Glc2-DAG) is the predominant glycolipid found in Bacillales and is also used as a membrane anchor for lipoteichoic acid (LTA) (By similarity) (388 aa)
