Glycosylation Information
Sugar Donor SpecificityUDP-Glc 
Acceptor Substrate SpecificitySRR1-GlcNAc-Glc
Experimental ValidationIn vivo and In vitro
ProductSRR1-GlcNAc-Glc-Glc
Donor SpecificityUDP-Glc
Function in Glycosylation pathway1) GlyG also responsible for the third-step glycosylation, it transfers UDP-glc on acceptor SRR1-GlcNAc-Glc to form acceptor SRR1-GlcNAc-Glc-Glc.
Additional Information1) GlyG has significantly higher activity toward UDP-Glc.
