The present invention relates to a microorganism variant having the ability to extracellularly produce heme, and more particularly to a metabolically engineered microorganism variant having the ability to extracellularly produce heme and a method of producing heme using the same. According to the present invention, heme, an organometallic compound which is increasingly used as a health food or food supplement for the treatment of porphyria, can be extracellularly secreted and produced in high yield using the microorganism variant, but not conventional chemical synthesis or enzymatic synthesis.

The present invention relates to a recombinant microorganism, to a method for producing alanine and to the use of the recombinant microorganism for the fermentative production of alanine.

Plants and plant tissue such as leaves comprising leghemoglobin are produced by modifying the genome of the plant or introducing leghemoglobin coding or regulatory sequences into the plant. Plants, leaves, fruits, tubers, roots, seeds, and protein compositions comprising leghemoglobin are provided. Protein compositions comprising leghemoglobin, such as isolates and concentrates, can be made from the plants, tissue, fruits, tubers, roots, seeds and leaves. Additionally, methods for generating and using plants, tissue, fruits, tubers, roots, seeds, leaves and protein compositions comprising leghemoglobin are disclosed.
