Method of continuously producing glutathione using photosynthetic membrane vesicles

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, γ-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.

MAMMALIAN EXPRESSION VECTORS

An expression vector for mammalian cells includes a selection cassette with a nucleotide sequence encoding a glutamine synthetase, operably linked to a PGK promoter and a pA signal. The vector may include the EASE element which is known to promote stable integration of the expression cassettes into the genome.
