Nitrites 38-45 leghemoglobin A Glycine max 22-25 560873-0 1977 Effect of nitrite upon leghemoglobin and interaction with nitrogen fixation. Nitrites 10-17 leghemoglobin A Glycine max 23-36 560873-2 1977 In the presence of leghemoglobin (0.1mM), a 3-fold enhancement of nitrogen fixation occurred but the inhibitory effect of nitrite was delayed. Nitrites 122-129 leghemoglobin A Glycine max 19-32 560873-3 1977 Spectra of leghemoglobin showed a rapid disappearance of the 574 nm and 541 nm peaks of oxyleghemoglobin the presence of nitrite. Nitrites 121-128 leghemoglobin A Glycine max 11-24 560873-5 1977 High nitrite levels could depress nitrogen fixation both by inactivation of nitrogenase and by conversion of leghemoglobin into an inactive form. Nitrites 5-12 leghemoglobin A Glycine max 109-122
