Prokaryotic long coiled-coil proteins. Schematic representation of prokaryotic long coiled-coil proteins not belonging to the ABC-ATPase family. Only proteins with at least 150 amino acids predicted to be in a coiled-coil are shown. Blue, coiled-coil domain; green, signal peptide; yellow, transmembrane domain. Functional domains as identified in the CDD  are circled in red. tlpC-1, tlpC-2, methyl-accepting chemotaxis proteins homologous to B.s. tlpC ; hmw2, cytadherence protein , CHLPS incA, incA, inclusion membrane proteins ; TolA, ; OspD, outer surface protein D , .
