Genes for seven putative serine proteases (ChpA–ChpG) belonging to the trypsin subfamily and homologous to the virulence factorpat‐1were identified on the chromosome ofClavibacter michiganensissubsp.michiganensis(Cmm) NCPPB382. All proteases have signal peptides indicating export of these proteins. Their putative function is suggested by two motifs and an aspartate residue typical for serine proteases. Furthermore, six cysteine residues are located at conserved positions. The genes are clustered in a chromosomal region of about 50 kb with a significantly lower G + C content than common forCmm. The geneschpA,chpBandchpDare pseudogenes as they contain frame shifts and/or in‐frame stop codons. The geneschpCandchpGwere inactivated by the insertion of an antibiotic resistance cassette. ThechpGmutant was not impaired in virulence. However,in plantathe titre of thechpCmutant was drastically reduced and only weak disease symptoms were observed. Complementation of thechpCmutant by the wild‐type allele restored full virulence.ChpCis the first chromosomal gene ofCmmidentified so far that affects the interaction of the pathogen with the host plant.
