Measurement of nitrogenase activity of intact legume symbionts in situ using the acetylene reduction assay

Creator:

Fishbeck, Kathleen Ann

Abstract:

The process of biological nitrogen fixation involves the enzymic reduction of atmospheric nitrogen (N₂) to ammonia (NH₃). The enzyme which catalyzes this reduction, nitrogenase, does not exhibit a high degree of substrate specificity. It also catalyzes the reduction of acetylene (C₂2H₂) to ethylene (C₂H₄). The reduction of C₂H₂ to C₂H₄...

The glutamine synthetases in soybean root nodules and free-living Rhizobium japonicum

Creator:

Guevara, Juan Garcia

Abstract:

Glutamine synthetase activity is present in both the cytosol and bacteroid fractions of soybean root nodules. Total activity measurements indicate that at least 90% of the activity in nodules is located in the cytosol. Results reported by McParland, et al. (29), showed that many properties of glutamine synthetase from nodule...
