在密歇根克拉维杆菌(clavibacter michiganenissubsp)染色体上发现了7个疑似丝氨酸蛋白酶(ChpA-ChpG)基因,这些基因属于胰蛋白酶亚家族,与毒力因子1同源。michiganensis NCPPB382 (Cmm)。所有的蛋白酶都有信号肽表示这些蛋白的输出。两个基序和一个典型丝氨酸蛋白酶的天冬氨酸残基表明了它们的推测功能。此外,6个半胱氨酸残基位于保守位置。这些基因聚集在一个约50 kb的染色体区域,其G + C含量明显低于普通形式cmm。geneschpA,chpBandchpDare假基因,因为它们包含帧移位和/或帧内停止密码子。基因pcpcg和基因pgg通过插入抗生素抗性盒而失活。突变体的毒力未受影响。然而,在植物中,突变体的滴度急剧降低,只观察到微弱的疾病症状。野生型等位基因对chpcmutant的补充恢复了完全的毒力。chpc是迄今为止鉴定的第一个影响病原菌与寄主植物相互作用的染色体基因。
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.
