Proteomic and Mutant Analysis of Hydrogenase Maturation Protein Gene in Symbiotic Nitrogen Fixation of .

yet important redox reaction between protons and electrons and H, thus mediating symbiotic interactions. The contribution of to this symbiosis and anti-oxidative damage was investigated using the (encoding maturation protein) mutant. The mutant grew a little faster than its parental 7653R and displayed decreased antioxidative capacity under HO-induced oxidative damage.
