Glycine max

reactive nitrogen species are able to react with two inactive forms (in terms of oxygen binding) of leghemoglobin: ferryl-leghemoglobin and nitrosyl-leghemoglobin. In both cases, the product of the reactions is metleghemoglobin. As metleghemoglobin can be reduced by a reductase found in the nodules, reactive nitrogen species could contribute to the recycling of these inactive forms to regenerate deoxyLb, the oxygen-binding form of Lb
