Alignment of the S. aureus SodA amino acid sequence with those of E. coli [P00448, P09157], S. typhimurium [P43019], L. pneumophila [P31108], B. subtilis [P54375], P. putida [P77928], L. monocytogenes [P28764], and the putative S. aureus enzyme [S54793] (only partially sequenced). Numbers represent the position of the amino acid sequence. Fe and Mn denote metal iron cofactor of enzyme. Residues in bold are predicted to bind metal iron cofactor. Boxed residues have been predicted to bind Mn²⁺. Asterisks pinpoint deletions, which discriminate Mn- from Fe-SOD.
