'''GLUTATHIONE S-TRANSFERASE P1-1 APO FORM 1'''
===GLUTATHIONE S-TRANSFERASE P1-1 APO FORM 1===




==Overview==
<!--  
Three-dimensional structures of the apo form of human pi class glutathione transferase have been determined by X-ray crystallography. The structures suggest the enzyme recognizes its substrate, glutathione, by an induced-fit mechanism. Compared to complexed forms of the enzyme, the environment around the catalytic residue, Tyr 7, remains unchanged in the apoenzyme. This observation supports the view that Tyr 7 does not act as a general base in the reaction mechanism. The observed cooperativity of the dimeric enzyme may be due to the movements of a helix that forms one wall of the active site and, in particular, to movements of a tyrosine residue that is located in the subunit interface.
The line below this paragraph, {{ABSTRACT_PUBMED_9665696}}, adds the Publication Abstract to the page
