T-synthase may utilize charge-charge interactions to modulate its activity, rejecting basic peptides over neutral and acidic peptide acceptors, T-synthase recognizes specific features of the peptide portion of the substrate, including overall charge and the presence of Gly, Phe, Tyr, and perhaps Pro at specific positions, up to four residues from the site of glycosylation, and indeed may use these features to modulate sites of Core 1 glycosylation |
