CC   -!- FUNCTION: Component of the core of the flagella. {ECO:0000305}.
CC   -!- SUBUNIT: The flagellum consists of two outer layers around a core that
CC       contains several antigenically related polypeptides.
CC   -!- SUBCELLULAR LOCATION: Periplasmic flagellum. Periplasm.
CC   -!- SIMILARITY: Belongs to the bacterial flagellin family. {ECO:0000305}.
