Abstract:
... The UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferases (GalNAc-Ts) catalyze mucin-type O-glycosylation by transferring α-N-acetylgalactosamine (GalNAc) from UDP- GalNAc to Ser or Thr residues of target proteins. We resolved the crystal structures of GalNAc-T7, a GalNAc-T capable of glycosylating consecutive sites, and of its complex with the donor substrate UDP-GalNAc. The N-terminal cataly ...
