FIG 1 — Sequence alignment of R. capsulatus CcoA homologues and its homology-based 3D structure. (A) Partial alignment of the R. capsulatus CcoA amino acid sequence with its homologues from selected proteobacteria. The conserved Met, His, and Tyr residues are highlighted, and their amino acid numbers in R. capsulatus CcoA are indicated (see Table S1 for the corresponding amino acid positions in the other species). (B) Homology model of R. capsulatus CcoA constructed with Swiss-Model (http://swissmodel.expasy.org) using the E. coli YaJR protein (PDB code 3WDO), which is the closest homologue of R. capsulatus CcoA (16% sequence identity), as the template.
