Figure 4. Effect of epoxomicin treatment on peptide levels; correlation with cleavage site.

For this analysis, only peptides with a single cleavage (i.e. N- or C-terminal peptides) or internal peptides that required cleavage at P1 sites which fell into the same group were considered. Peptides that reflected internal fragments requiring distinct cleavages were excluded from this analysis. The number of peptides found in each group is indicated.
