SYSTEMATIC NAME
IUBMB Comments
membrane-derived-oligosaccharide-6-(glycerophospho)-D-glucose:membrane-derived-oligosaccharide-D-glucose glycerophosphotransferase
beta-Linked glucose residues in simple glucosides, such as gentiobiose, can act as acceptors. In the presence of low concentrations of acceptor, free cyclic 1,2-phosphoglycerol is formed.
