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.

Dual mass spectrometry-cleavable crosslinking reagents for protein-protein interactions

Described are dual mass-spectrometry-cleavable cross-linkers that can be cleaved selectively using two differential tandem mass-spectrometric techniques such as collision induced dissociation (CID) or electron transfer dissociation (ETD), i.e., a dual cleavable crosslinking technology (DUCCT) cross-linker. When used to cross-link a macromolecule, such as a peptide, MS/MS fragmentation produces two signature complementary mass spectra of same cross-linked peptides, the analysis of which gives rise to high confidence in characterizing the structures of the cross-linked macromolecules as well as sites of interactions. Also described, are methods of making and using DUCCT cross-linkers.
