Hydroxylamine 13-26 leghemoglobin A Glycine max 201-214 16663546-7 1984 However, ferric leghemoglobin was formed by treating the nodule slices with hydroxylamine, and this was confirmed by complexing the ferric leghemoglobin to acetate, fluoride, or nicotinic acid. Hydroxylamine 76-89 leghemoglobin A Glycine max 16-29 27661977-3 2016 Experiments were conducted with phytoglobins from rice, tomato, and soybean along with human neuroglobin and soybean leghemoglobin that reveal hydroxylamine binding as the rate-limiting step. Hydroxylamine 143-156 leghemoglobin A Glycine max 117-130 27661977-4 2016 For hexacoordinate hemoglobins, binding is limited by the dissociation rate constant for the distal histidine, while leghemoglobin is limited by an intrinsically low affinity for hydroxylamine. Hydroxylamine 179-192 leghemoglobin A Glycine max 117-130
