Alignment and sequence comparison of PaAhpC with AhpC proteins from other bacteria. The encoded amino acid sequences were aligned according to the two highly conserved active cysteines (Cys⁴⁷ as the catalytic Cys and Cys¹⁶⁶ as the resolving Cys), which are indicated by squares. The positions of the introduction of additional cysteine residues (Cys⁷⁸ and Cys¹⁰⁵) are indicated by a triangle. ‘^*’ indicates positions which have a single, fully conserved residue. The percentage of the number of identical amino acids shared with PaAhpC is shown in parentheses at the end of the last lines. The abbreviations for the amino acid sequences of AhpC proteins from various species are as follows: Pseudomonas aeruginosa PAO1 (PaAhpC; NP_248829); Thauera sp. MZ1T (TsPrx; ACR02206); E. coli (EcAhpC; AJE54932); Salmonella enterica subsp. enterica serovar Typhimurium (StAhpC; AIE04547); Acinetobacter lwoffii SH145 Prx (AlPrx; EEY91350); Methylosinus trichosporium (MtPrx; WP_003609555); Azospirillum sp. B510 (AsAhpC; BAI75915); Azospirillum brasilense Sp245 (AbAhpC; AAY88877).
