The first codon of the nodS sequence (gtg) has been translated in this NodS protein as Val1, which is different from the Met1 residue occurring in NodS isolated from Bradyrhizobium japonicum WM9. The present protein is therefore a single-site variant of the natural polypeptide. Source: (gene. exp.) Bradyrhizobium sp.
