Comparison of FNR/FnrL homologues. Similarities of FnrL from Rba. capsulatus and Rba. sphaeroides and their differences to FNR from E. coli. Fe/S motif was taken from the N-terminus (solid) and HTH domain was taken from the C-terminus (dashed). Red colored amino acids denote critical residues, green denote similarities between Rhodobacter species, blue denote similarities between E. coli and Rhodobacter species, grey are unique to each organism and redundantly represented by ‘.’, ‘*’ and ‘!’
