Abstract excerpt
The mode of inactivation of glutathione S-transferase isoenzyme 3-3 from rat by the active site-directed inhibitor 2-(S-glutathionyl)-3,5,6-trichloro-1,4-benzoquinone (GSTCBQ) has been investigated by a combination of site-specific mutagenesis and mass spectrometric analysis of the sites of react...
