Abstract
Tryptic digests of chromatographically pure samples of flagellin prepared from a normal flagellar strain and its curly mutant in Salmonella abortus-equi were compared with each other ionophoretically and chromatographically. The two flagellins differ in only one among resultant 35 peptides. The peptides differing between two flagellins have the following characters: 1) they do not contain arginine, histidine and tyrosine; 2) the charge difference are not observed between them; 3) the Rf value of the peptide in curly flagellin is approx. 3.5 times higher than that in normal flagellin.
