IntEnz Enzyme Nomenclature


Accepted name:
poly(glycerol-phosphate) α-glucosyltransferase
Other names:
UDP glucose-poly(glycerol-phosphate) α-glucosyltransferase
uridine diphosphoglucose-poly(glycerol-phosphate) α-glucosyltransferase
tagE (gene name)
UDP-glucose:poly(glycerol-phosphate) α-D-glucosyltransferase
Systematic name:
UDP-α-D-glucose:4-O-{poly[(2R)-glycerophospho]-(2R)-glycerophospho}-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol α-D-glucosyltransferase (configuration-retaining)



Involved in the biosynthesis of poly glycerol phosphate teichoic acids in bacterial cell walls. This enzyme, isolated from Bacillus subtilis 168, adds an α-D-glucose to the free OH groups of the glycerol units. The enzyme has a strong preference for UDP-α-glucose as the sugar donor. It has no activity with poly(ribitol phosphate).
