  • Patent number: 11499174
    Abstract: The present invention relates to a method of producing glutathione, wherein photosynthetic membrane vesicles and enzymes catalyzing glutathione synthesis are combined and glutamate, cysteine and glycine are used as reaction substrates. As enzymes catalyzing glutathione synthesis, ?-glutamylcysteine synthetase and glutathione synthetase may be used together, or bifunctional glutathione synthetase may be used alone. According to the conventional methods, there is a problem in that expensive adenosine triphosphate should be continuously supplied when glutathione is produced. However, according to the present invention, since photosynthetic membrane vesicles are used as a source to regenerate adenosine triphosphate, it is possible to continuously produce glutathione without additionally adding adenosine triphosphate, thereby reducing production costs of glutathione.
