Figure 6: Co-expression of PP1 and inhibitor-2. Top: Phosphatase activity in the IPTG induced bacterial extracts that contains genes for PP1 alone, PP1 and I-2 both and I-2 alone. Control samples are bacterial extracts without IPTG induction. Bottom: Western blot analysis in IPTG induced bacterial extracts: For I-2 in only I-2 containing bacteria and in co-transfected bacteria; For PP1 in only PP1 containing bacteria and co-transfected bacteria.
