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: | Leghemoglobin is a globin protein, constituted by a heme group(protoporphyrin XI) and a single polypeptide, which binds oxygen for transportation.

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). | 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). | 2.
