title: Helicobacter pylori possesses four coiled-coil-rich proteins that form extended filamentous structures and control cell shape and motility.
abstract: We identified two additional genes of Helicobacter 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, all ccrp mutants displayed significantly reduced motility.
