(A) Map of S. typhimurium sodC region. An ORF encoding a predicted protein with homology to the Ail protein of Yersinia enterocolitica and ORFs highly homologous to genes that encode bacteriophage λ tail proteins are designated. (B) Sequence alignment of S. typhimurium and E. coli SodC proteins. The full-length SodC proteins from S. typhimurium and E. coli (22) are 54% identical at the amino acid level. The S. typhimurium sodC gene encodes a protein of 18.3 kDa predicted size. The protein possesses a typical hydrophobic NH2 terminus signal sequence (underlined); cleavage would produce a mature protein of 16.3 kDa predicted size.
