Variation in bacterial flagellins: from sequence to structure (2006)

Scott A. Beatson, Tohru Minamino, Mark J. Pallen

We chose to undertake a comprehensive analysis of all available bacteral flagellin sequences in light of the 3D structure of Salmonella typhimurium flagellin. Remarkable conservation in the regions...

Variation in bacterial flagellins: from sequence to structure (2006)

Beatson, Scott A., Minamino, Tohru, Pallen, Mark J.
