CC   -!- FUNCTION: Component of the outer layer of the flagella.
CC   -!- SUBUNIT: The flagellum consists of an outer layer composed of two
CC       sheath proteins, flaA1 (44 kDa) and flaA2 (35 kDa) around a core that
CC       contains three proteins flaB1 (37 kDa), flaB2 (34 kDa) and flaB3 (32
CC       kDa).
CC   -!- SUBCELLULAR LOCATION: Periplasmic flagellum. Periplasm.
