12686490-5	2003	Inhibition studies with the GSTP1-1 mutants C47S, C101S and the double mutant C47S/C101S showed that cysteine 47 is the key residue in the interaction between quercetin and GSTP1-1.	Cysteine	101-109	glutathione S-transferase pi 1	Homo sapiens	28-35	
12686490-5	2003	Inhibition studies with the GSTP1-1 mutants C47S, C101S and the double mutant C47S/C101S showed that cysteine 47 is the key residue in the interaction between quercetin and GSTP1-1.	Cysteine	101-109	glutathione S-transferase pi 1	Homo sapiens	173-180	
12686490-8	2003	Nevertheless, the results of the present study indicate that quinone-type oxidation products of quercetin likely act as specific active site inhibitors of GSTP1-1 by binding to cysteine 47.	Cysteine	177-185	glutathione S-transferase pi 1	Homo sapiens	155-162
