Reaction: UDP-glucose + glycoprotein D-mannose = UMP + glycoprotein 6-(D-glucose-1-phospho)-D-mannose
Other names: UDP-glucose:glycoprotein glucose-1-phosphotransferase; GlcPTase; Glc-phosphotransferase; uridine diphosphoglucose-glycoprotein glucose-1-phosphotransferase
Systematic name: UDP-glucose:glycoprotein-D-mannose glucosephosphotransferase
Comments: Penultimate mannose residues on oligo-mannose type glycoproteins can act as acceptors.
