We identified two additional genes ofHelicobacter pylori encoding Ccrp proteins. All four Ccrps have different multimerization and filamentation properties and different types of smallest subunits and do not copurify, suggesting a system of individual Ccrp filaments. Despite the presence of morphologically unaltered flagella, allccrp mutants displayed significantly reduced motility.
