چکیده
This article describes data related to a research article titled "The Busulfan Metabolite EdAG Irreversibly Glutathionylates Glutaredoxins" [1]. EdAG is an electrophilic GSH analog formed in vivo from busulfan, which is used in hematopoietic stem cell transplants. EdAG glutathionylates Glutaredoxins (Grx's) but not glutathione transferase A1-1 (GSTA1-1) in vitro. This article includes a complete NMR characterization of synthetic EdAG including homonuclear and heteronuclear correlation spectra. Also included are mass spectra of peptides from Grx's or GSTA1-1 that have cys residues that do not react with EdAG.

Dehydroalanine analog of glutathione: an electrophilic busulfan metabolite that binds to human glutathione S-transferase A1-1.
Elimination of hydrogen sulfide from glutathione (GSH) converts a well known cellular nucleophile to an electrophilic species, gamma-glutamyldehydroalanylglycine (EdAG). We have found that a sulfonium metabolite formed from GSH and busulfan undergoes a facile beta-elimination reaction to give EdAG, which is an alpha,beta-unsaturated dehydroalanyl analog of GSH. EdAG was identified as a metaboli...
