Helicobacter pylori Possesses Four Coiled-Coil-Rich Proteins That Form Extended Filamentous Structures and Control Cell Shape and Motility

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 morphol...

Description
Summary: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.
