FIGURE 7.
ppGalNAc T5 and T12 enhancement products versus experimentally determined sites of glycosylation. ppGalNAc T5 against EA2 (panel A) and ppGalNAc T12 against MUC5AC (panel B). Gray bars represent experimentally determined [3H]GalNAc incorporation obtained by Edman sequencing (uncorrected for background or sequence lag), and black bars represent random peptide-derived enhancement value products.
