Figure 3. N-terminal amino acid sequence analysis. The first 14 residues of SMFliC showed considerable identity to other flagellins. The highest degree of identity was found with the Serratia marcescens flagellin (78.6%). Stenotrophomonas maltophilia flagellin also showed identity to flagellins of Shigella sonnei, Escherichia coli, and Proteus mirabilis (71.4%), and the lowest identity was found with Pseudomonas aeruginosa flagellin (57.2%). The numbers on top indicate the amino acid position.
