Term Name: | glycogenin glucosyltransferase activity |
---|---|
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. |
