The inability of 5-cholesten-3-one to serve as substrate for the bacterial ketosteroid isomerase was noted in the original publication ( Investigations of the Pseudomonas ketosteroid isomerase based on deuterium and tritium labeling of reactants provided evidence for direct and stereospecific diaxial proton transfer from the 4 to the 6 position ( The role of glutathione in the mammalian GSTs catalyzing the ketosteroid isomerization was not evident, since the bacterial isomerase did not require a cofactor ( a value of the thiol of glutathione is lowered by 2.5 units from 9.2 in solution to 6.7 when bound to GST A1-1 ( a value from 6.7 to 7.2 when Tyr9 was mutated into Phe ( a of Tyr9 is 8.1 in the free GST A1-1, but the value increases to 9.2 when glutathione is bound ( a appears dependent on the ionized thiolate, since S-methylglutathione is without effect on the ionization of Tyr9
The protective effect of hepatocyte growth factor against cell death in the hippocampus after transient forebrain ischemia is related to the improvement of apurinic/apyrimidinic endonuclease/redox factor-1 level and inhibition of NADPH oxidase activity
