Figure 1

Sequence alignment of SQR from A. ferrooxidans (A.ferro) with SQRs from Thiobacillus denitrificans (T.denit), Tolumonas auensis (T.auens), Aquifex aeolicus (A.aeoli) and Acidianus ambivalens (A.ambiv) and FCC (flavocytochrome c sulfide dehydrogenase) from Chromatium vinosum. Conserved residues are shown on a red background, whereas residues with similar chemical properties are shown in red. The sequence identities between A.ferro and T.denit, T.auens, A.aeoli, A.ambiv and FCC are 57, 51, 40, 27 and 25%, respectively. Sequence alignment was performed using the program ClustalW (Thompson et al., 1994 ▶) and the figure was generated with the program ESPript (Gouet et al., 1999 ▶).
