'''Introduction'''

Leghemoglobin is a protein that is required by Legume plants in order to fix nitrogen by participating in the Nitrogen Fixation pathway. Leghemoglobin functions by keeping the oxygen at a specific low concentration to the bacteroids to allow for respiration, but at the same time, this low concentration keeps the oxygen out of the nitrogen cycle so it doesn’t inhibit the nitrogenase activity (Ref 1).

Leghemoglobin is a protein that is required by Legume plants in order to fix nitrogen by participating in the Nitrogen Fixation pathway. It is found in legumes such as cowpea, soybeans, alfalfa, and other different types of beans. Leghemoglobin functions by keeping the oxygen at a specific low concentration to the bacteroids to allow for respiration, but at the same time, this low concentration keeps the oxygen out of the nitrogen cycle so it doesn’t inhibit the nitrogenase activity (Ref 1).

Leghemoglobin is a globin protein, constituted by a heme group(protoporphyrin XI) and a single polypeptide, which binds oxygen for transportation. ~~Other major proteins~~ in ~~this group are~~ ~~myoglobin and hemoglobin~~ (Ref 5).

Leghemoglobin is a globin protein, constituted by a heme group(protoporphyrin XI) and a single polypeptide, which binds oxygen for transportation. (Ref 5). It is hypothesized that Leghemoglobin can be formed by one of the two ways:

1) The Rhizobium bacteroid (Ref 2) is thought to synthesize the heme group in the root nodules of the legume, where it then gives the plant the heme to complete the synthesizing of the Lb (Ref 1).

2) The plant itself has also been thought to possibly produce the heme itself, in the mytochondria of the plant cells. It then combines with the peptide sequence to complete the whole protein (Ref 1).
