Architectonics of a bacterial flagellin filament subunit.
Flagellins of two Escherichia coli strains and their tryptic fragments were studied by different methods. Probabilities of secondary structure formation were also calculated for all flagellins with a known primary structure. The obtained data permit one to suggest a model for the flagellin molecule consisting of a central part responsible for antigenic properties and terminals responsible for polymerization. The central part is variable in length from a few amino acid residues to three-four hundred depending on the bacterial species. The terminal parts consist of about 160 amino acid residues from the N-end and 100 from the C-end.
