Characterization of flagellin from Clostridium chauvoei.
Differential centrifugation and cesium chloride-equilibrium centrifugation were used to purify the flagella from the strain Okinawa of the formalin-fixed Clostridium chauvoei. SDS-PAGE profile of purified flagella showed that a major protein band with a molecular mass of 46 kDa, corresponding to the flagellin monomer, and at least two minor protein bands with molecular masses of approximately 73 and 100 kDa were found. The amino acid composition of C. chauvoei flagellin was similar to the flagellin of Salmonella typhimurium and Bacillus subtilis. In addition, C. chauvoei flagellin monomer shared limited sequence homology with the N-terminal amino acid sequence reported for other bacterial flagellins. N-terminal sequences of two minor bands corresponded to the flagellin monomer, indicating that higher molecular mass bands were polymeric forms of the flagellin monomer.
