Thioxodipeptides Gly - thio - Lys ( GtK ) , Ala - thio - Lys ( AtK ) , and Ala - thio - Arg ( AtR ) in which the amide group has been modified to a thioxoamide were made into dications by electrospray ionization and converted to cation - radicals , ( GtK + 2H ) ( + * ) , ( AtK + 2H ) ( + * ) , and ( AtR + 2H ) ( + * ) , by electron transfer dissociation ( ETD ) tandem mass spectrometry using fluoranthene anion - radical as an electron donor .
