CC   -!- FUNCTION: Component of the outer layer of the flagella.
CC   -!- SUBUNIT: The flagellum consists of an outer layer composed of repeating
CC       units of FlaA around a core that contains one or all of five
CC       antigenically related polypeptides.
CC   -!- SUBCELLULAR LOCATION: Periplasmic flagellum. Periplasm.
