Identification of cleaved CTDs and their putative cleavage sites.

a The semi-tryptic peptides identified by MS/MS are shown underlined, together with the six amino acid residues immediately N-terminal to the proposed cleavage sites (/).b The Mascot score shown is for the underlined semi-tryptic peptide (shown in previous column). Scores above 35 were significant according to Mascot (pc The total number of CTD peptides identified.d The peptide identified was from HagA since Kgp was not present in this mutant.e This Kgp sequence cannot be distinguished from an identical sequence found in the expected cleavage site sequence of HagA (PG1837).Identification of cleaved CTDs and their putative cleavage sites.
