Figure 4

Multiple sequence alignment of SmNifA, BjNifA, and its mutant derivatives. Only regions near the mutated residues on BjNifA are shown. Dots indicate discontinuity of the alignment. Numbers above the sequences indicate amino acid positions mutated in BjNifA. Numbers below the alignment show amino acid positions of BjNifA. Boxes indicate the highly conserved regions in the EBP proteins (9, 10). The central domains of BjNifA and SmNifA are 68% identical, whereas the degree of identity of the whole family is around 40%.
