== Publication Abstract from PubMed ==
The retro-analogue of glutathione disulfide was bound to the GSSG binding site of crystalline glutathione reductase. The binding mode revealed why the analogue is a very poor substrate in enzyme catalysis. The observed binding mode difference between natural substrate and retro-analogue is explained.

The binding of the retro-analogue of glutathione disulfide to glutathione reductase.,Janes W, Schulz GE J Biol Chem. 1990 Jun 25;265(18):10443-5. PMID:2355009<ref>PMID:2355009</ref>
