Glycogenin primer is glucosylated by:
Ans. A. UDP Glucose(Ref: Harper 31/e page 164)Glycogenin, a 37 kDa protein is glucosylated on specific tyrosine residue by UDP glucose.Glycogenenin catalyses transfer of 7 glucose residue from UDP-Glc, in l-4 linkage to form Glycogen primer.Further Glucose on glycogen primer are added by Glycogen Synthase to nonreducing end till growing chain is at least 11 glucose residue long.
