Proteomic analysis of the N-terminal peptides from the proteome of the wild-type strain DGCC7796 and mutant DGCC7796:metAPH206Q. Post-translational processing of the N-terminal methionine was detected in both proteomes but it was less abundant in the mutant strain. N represents unprocessed peptides while Y stands for processed peptides.
