Is leghemoglobin a tertiary protein

WitrynaAlthough green plants contain no hemoglobin, a red protein, called leghemoglobin, has been discovered in the root nodules of leguminous plants. It seems to be produced by the nitrogen-fixing bacteria of the root nodules and may be involved in the reduction of atmospheric nitrogen to ammonia and amino acids.
