Identification of unprocessed proteases in the aprV5 mutant and aprV5ΔC strains by mass spectrometry.

aCoverage denotes the percentage of the full length protein sequence that has been matched to the MS data.bBest MASCOT score obtained between analyses from different gel pieces excised from identical gels.cMS value denotes the number of peptides matched to the MS data corresponding to sequences from within a specific region of the protein. MSMS value denotes the number of these peptides matches of which the sequences have been confirmed by MSMS analysis.
