Inhibition of human placenta glutathione transferase P1-1 by calvatic acid.

Abstract

The inhibition mechanism of the dimeric human placenta glutathione transferase (GST P1-1) by the antibiotic p-carboxyphenylazoxycyanide (calvatic acid) has been investigated at pH 7.0 and 30.0 degrees C. Experiments performed at different calvatic acid/GST P1-1 molar ratios indicate that one mole of calvatic acid inactivates one mole of the homodimeric… (More)
