Diagram showing protein domains and sequence-based regions of fliC. Top: the C1, V, and C2 regions and C1a, C1b, C2a, and C2b subregions of E. coli H7, recognized in comparisons of E. coli DNA sequences described in this paper. Center: the C1, V, and C2 regions of S. enterica LT2 located by homology with E. coli H7. Bottom: the domains (D1, D2, and D3) identified in the flagellin protein of S. enterica serovar Typhimurium LT2 (31).
