O-GlcNac transferase (OGT) catalyzes the addition of N-acetylglucosamine (GlcNAc) to serine or threonine residues by O-glycosylation. OGT contains 2 subunits: a 110 kDa and a 78kDa. The 110 kDa subunit contains a superhelical domain with 13 tetratricopeptide (TPR) repeats. The TPR motif consists of 34 amino acids and mediates protein-protein interactions. For details see Human O-GlcNAc transferase.
