Question

Three points why leghomoglobin is called oxygen scavenger

Answer 1

In plants colonised by Rhizobium, such as or , the presence of in the root nodules would reduce the activity of the oxygen-sensitive , which is an enzyme responsible for the fixation of atmospheric nitrogen. Leghemoglobin buffers the concentration of free oxygen in the of infected plant cells to ensure the proper function of root nodules. Leghemoglobin has a high affinity for oxygen (~ 0.01 µM), about ten times higher than the β chain of human hemoglobin. This allows an oxygen concentration that is low
