RESUMO
A partial amino-acid sequence of Bacillus subtilis 168 flagellin is presented. The region of unassigned sequence in this 304-residue polypeptide chain spans residues 158-173. Comparison of the 27-residue aminoterminal CNBr peptide of B. subtilis 168 flagellin with that derived from the flagellin of the serologically unrelated strain of B. subtilis, W23, shows only three conservative substitutions, whereas the 16-residue carboxyl-terminal peptides derived from these flagellins were identical. The comparison of the very limited sequence information available on the flagellins of Salmonella and Proteus with that on B. subtilis indicates homology between these proteins.
