Characterization of the proteins of the Caulobacter crescentus flagellar filament. Peptide analysis and filament organization.

Abstract

During each cell division cycle, the bacterium Caulobacter crescentus synthesizes a single polar flagellum and then releases this flagellum into the culture medium.Two flagellins, Fla A (25,000 daltons) and Fla B (27,500 daltons), are recovered from the total population of released flagellar filaments in a ratio of 4 to 1, respectively.These two proteins have been shown to be immunologically cross-reactive (Lagenaur, C., and Agabian, N.
