  • a Alignment positions of unambiguously determined nucleotides represented in all sequences were used for pairwise comparisons of dsrA (968 positions),dsrB (668 positions), DsrA (322 positions), and DsrB (224 positions). Values for DsrA/dsrA are below the diagonal, and those for DsrB/dsrB are above the diagonal.
