Accepted name: membrane-oligosaccharide glycerophosphotransferase

Reaction: Transfer of a glycerophospho group from one membrane-derived oligosaccharide to another

Other name(s): periplasmic phosphoglycerotransferase; phosphoglycerol cyclase

Systematic name: membrane-derived-oligosaccharide-6-(glycerophospho)-D-glucose:membrane-derived-oligosaccharide-D-glucose glycerophosphotransferase

Comments: β-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.
