FIG 1.
Alignment of the S. Typhimurium IprA protein with homologs present in other Enterobacteriaceae genera. Yellow highlighting indicates amino acid identity or strong similarity (in at least four of the proteins). The E values for the aligned proteins range between 10−110 and 10−50. The accession numbers for sequences analyzed here are as follows: NP_459369 (Salmonella enterica serovar Typhimurium LT2), NP_414909 (Escherichia coli MG1655), NP_706193 (Shigella flexneri 2a strain 301), WP_044699331 (Citrobacter freundii), KPS97271 (Enterobacter cloacae), WP_006818715 (Yokenella regensburgei), and WP_004386860 (Cronobacter sakazakii). Asterisks indicate amino acids that are identical across all proteins; double dots indicate amino acids highly conserved across all proteins. A single dot indicates some high amino acid conservation coupled with divergence at this position.
