Fig. 6. Effect of roscovitine and DRB on the phosphorylation of GST-CTD by CDK7/His6-CycH/MAT1, His6-CDK8/CycC and His6-CDK9/CycT1.

Fig. 6

Roscovitine and DRB were added to the kinase reaction mixtures at concentrations indicated and kinase reactions were carried out as described in Materials and Methods. Lanes 1, 6 and 11 are kinases without substrate. The graph shows the percentage of the kinase activity as compared to their corresponding activity without inhibitors.
