Figure 3From: A new classification system for bacterial Rieske non-heme iron aromatic ring-hydroxylating oxygenasesGrouping of ferredoxin components from standard RHO enzymes with the conserved sequence alignments. The amino acid residues involved in binding to [2Fe-2S] (CXHXnCXXH) and [3Fe-4S] (CX5CXnC) cluster are indicated by highlighted characters. Fdx3 was used as an outgroup. The names of bacterial strains are indicated after the enzyme names.Back to article page
