Figure 2. . The coverage of the DSTP sequence by peptides identified by de novo sequencing programs Novor and PepNovo+ (PN+). Nov.2 – only the part of the peptide predicted by Novor, with single amino acid accuracy > 50 (minimum length is 6 residues) was used for coverage. In the case of PepNovo+ the symbol “X” marked the matching residual mass with a correctly identified TAG. EDMAN: the N-terminal fragment calculated by the mass difference of peptides is marked red; green designates the C-terminal fragment; “X” designates a fragment for which the mass is known, but sequence not determined.
