Direct Detection Of A Globin-Derived Radical In Leghaemoglobin Treated With Peroxides
Introduction Introduction to Leghaemoglobin Leghaemoglobins (Lb) are a homogeneous group of monomeric proteins with a molecular mass of ∼16,000. They are mainly distributed in nitrogen-fixing root nodules of leguminous plants. The contribution of leghaemoglobin in these nodules is to aid the transport of oxygen into the bacteroids (nitrogen-fixing symbiotic bacteria). Nitrogen fixation is essential to plant growth because it is the process of taking nitrogen out of the atmosphere and
