The Influence of Some Polyphenols on Human Erythrocytes Glutathione S-Transferase Activity

Authors: Mustafa Erat


Glutathione S-transferase was purified from human erythrocytes and effects of some polyphenols were investigated on the enzyme activity. The purification procedure was performed on Glutathione-Agarose affinity chromatography after preparation of erythrocytes hemolysate with a yield of 81%. The purified enzyme showed a single band on the SDS-PAGE. The effects of some poliphenolic compounds such as catechin, dopa, dopamine, progallol and catechol were examined on the in vitro GST activity. Catechin was determined to be inhibitor for the enzyme, but others were not effective on the enzyme as inhibitors or activators. IC50 value -the concentration of inhibitor which reduces enzyme activity by 50%- was estimated to be 10 mM. Ki constants were also calculated as 6.38 ± 0,70 mM with GSH substrate, and 3.86 ± 0,78 mM with CDNB substrate using the equations of graphs for the inhibitor, and its inhibition type was determined as non-competitive.

Keywords: Drug resistance, Glutathione S-transferase, Inhibition.
