Peptide transporter, SapABCDF. Mutants are more sensitive than the wild type to wheat alpha-thionin and to snakin-1, which is the most abundant antimicrobial peptide from potato tubers. They were also less virulent than was the wild-type strain in potato tubers: lesion areas were 37% that of the control, and the growth rate was two orders of magnitude lower. Thus, the interaction of antimicrobial peptides from the host with the sapA-F operon from the pathogen plays a similar role in animal and in plant bacterial pathogenesis (López-Solanilla et al. 1998).
