Figure 8. PP7 dephosphorylates HRB1.

Figure 8

(A) Phosphorylation status of HRB1∶GFP from transgenic plants treated with or without lambda phosphatase or Na3VO4. (B) Phosphorylation status of HRB1∶GFP from transgenic plants treated with partially purified GFP, PP7∶GFP (PP7G), mutated PP7∶GFP (PP7mG), and PP7∶GFP (PP7G) in the presence of Na3VO4. (C) Gel showing the partially purified PP7G, PP7mG, and GFP proteins. (D) Phosphorylation status of HRB1∶Myc in the leaves of 3-week-old Col or pp7 in the dark or under 4.93 µmol/m2/s blue light for 2 hours. Ponceau S staining revealed more proteins loaded in the Ws lane under blue light.
