Table II Summary of peptide and protein features. Fully-tryptic= both termini are either tryptic cleavage sites ([K/R][not-P]) or at the N- or C-terminus of a mapped protein. Some nontryptic termini can be explained by signal peptide cleavage or other natural post-translational cleavage. See text for further details
