Table 1. Effect of HEP and JNK proteins on GST activity.

The recombinant proteins of HEP and JNK were incubated with the different GST splice forms in 1:1 molar ratio for 5 min at room temperature. The percentage inhibition of GST activity was calculated using a reaction that contained no kinase proteins as control. No inhibition of GST activity of GSTD1-1 by JNK protein was detected. Results are means±S.D. for at least four independent experiments.

GST	Inhibition of GSTs by HEP (%)	Inhibition of GSTs by JNK (%)
D1-1	54.64±3.83	No inhibition detected
D2-2	53.29±7.71	85.35±6.72
D3-3	23.71±1.88	44.64±6.92
D4-4	29.27±2.99	68.45±4.00
