Activating Compound

Activating Compound Comment Organism Structure
H2O2 inhibits cytosolic GSTs and activates microsomal GSTs Rattus norvegicus

Inhibitors

Inhibitors Comment Organism Structure
H2O2 inhibits cytosolic GST by about 65% and activates microsomal GST to about 175% Rattus norvegicus
additional information presence of superoxide dismutase and catalase reduces the activity of the microsomal GST isozyme, but only catalase can reduce the activity of the cytosolic GST Rattus norvegicus
superoxide anion generated by a Fe3+/ascorbate system, inhibits cytosolic GSTs and microsomal GSTs by 30% and 65%, respectively. Addition of 2 mM DTT fails to completely reverse microsomal GST inhibition elicited by Fe3+/ascorbate, recovering only about 10% of this activity, but it completely reverses the inhibitory effect of Fe3+/ascorbate on cytosolic GST activity Rattus norvegicus
