step 4 Irreversible/directional

UDP-glucose + glycogenin–Tyr-OH → glycogenin–Tyr-O-glucose + UDP; repeated additions form a short alpha(1→4)-glucosyl primer

Converts UDP-glucose Glycogenin-Tyr-OH into Glycogenin-Tyr-O-glucose UDP Repeated additions form a short alpha(1→4)-glucosyl primer

Notes

Glycogenin is an autoglycosylating protein that uses UDP-glucose and divalent cation (typically Mg2+). It creates the required primer, usually about 8 residues long, because glycogen synthase cannot initiate a new chain de novo.
