Alignment of amino acid sequences of RoxA orthologs. Amino acid residues of RoxA orthologs that were identical to those of RoxAXsp are indicated by dots. Residues different from those in RoxAXsp are given by the 1-letter amino acid code. Heme binding and MauG motifs as well as important residues in RoxAXsp are emboxed. Conserved cysteine residues that contribute to disulfide bridges are connected with solid lines. Numbering of residues refers to that of RoxAXsp, as described in reference 9. RoxACcoT, RoxA from Corallococcus coralloides type strain (DSMZ 2259).
