Leghemoglobin
Leghemoglobin
Leghemoglobin (pronounced: leɡˈhiːməʊˌɡloʊbɪn) is a hemoprotein found in the root nodules of leguminous plants. It is a nitrogen-fixing bacterium that aids in the symbiotic relationship between legumes and certain bacteria.
Etymology
The term "leghemoglobin" is derived from the words "legume" and "hemoglobin". "Legume" is a type of plant that includes peas, beans, and lentils, while "hemoglobin" is a protein in red blood cells that carries oxygen.
Function
Leghemoglobin functions similarly to hemoglobin in animals. It binds to oxygen and delivers it to the bacteria in the root nodules. This process allows the bacteria to convert atmospheric nitrogen into a form that the plant can use for growth.
