Abstract
Flagellins of two Escherichia coli strains have been investigated by limited proteolysis and scanning microcalorimetry. It has been shown that a monomer flagellin consists of two parts: a central one cooperatively melting, rather resistant to proteases, and the other without a stable tertiary structure and thus easily degrading terminals. Just these terminals acquire a regular structure during polymerization. Core fragments of the two strains have been isolated and characterized.Keywords
