glycogenin glucosyltransferase activity

Term ID

GO:0008466

Synonyms

• 1,4alpha-glucan-protein synthase (UDP-forming) activity
• alpha-1,4-glucan-protein synthase (UDP-forming) activity
• glycogenin activity
• priming glucosyltransferase activity
• UDP-alpha-D-glucose:glycogenin alpha-D-glucosyltransferase activity
• UDP-glucose:glycogenin glucosyltransferase activity

Definition

Catalysis of the reaction: UDP-glucose + glycogenin = UDP + glucosylglycogenin. This first reaction is a self glucosylation. Further UDP-glucose goups are added to the [1,4-alpha-D-glucosyl](n) group of glycogenin until a length of about 5-13 residues. 2.4.1.186
