The major components of the periplasmic flagella of the spirochaete Serpulina (Treponema) hyodysenteriae strain C5 were purified and characterized. We demonstrate that the periplasmic flagella are composed of five major proteins (molecular masses 44, 37, 35, 34 and 32 kDa) and present their location, N-terminal amino acid sequence and immunological relationship. The 44 kDa and the 35 kDa protein are on the sheath of the periplasmic flagellum, whereas the 37, 34 and 32 kDa protein reside in the periplasmic flagellar core. The two sheath flagellar proteins are immunologically related but have different N-terminal amino acid sequences. The N-terminus of the 44 kDa protein shows homology with the sheath flagellins of other spirochaetes, but the 35 kDa protein does not. The three core proteins are immunologically cross-reactive and their N-terminal amino acid sequences are almost, but not completely, identical, indicating that the core proteins are encoded by three distinct genes. The core proteins show extensive N-terminal sequence similarities and an immunological relationship with periplasmic flagellar core proteins of other spirochaetes.

D005407 Flagella A whiplike motility appendage present on the surface cells. Prokaryote flagella are composed of a protein called FLAGELLIN. Bacteria can have a single flagellum, a tuft at one pole, or multiple flagella covering the entire surface. In eukaryotes, flagella are threadlike protoplasmic extensions used to propel flagellates and sperm. Flagella have the same basic structure as CILIA but are longer in proportion to the cell bearing them and present in much smaller numbers. (From King & Stansfield, A Dictionary of Genetics, 4th ed) Flagellum
D005408 Flagellin A protein with a molecular weight of 40,000 isolated from bacterial flagella. At appropriate pH and salt concentration, three flagellin monomers can spontaneously reaggregate to form structures which appear identical to intact flagella.
