Figure 1.
Phosphorylation and release of TSP9 from the thylakoid membrane. (A) Autoradiogram of 32P-labeled thylakoid proteins separated by SDS/PAGE after light-induced phosphorylation of the membranes in the presence of [γ-32P]ATP. The positions of major known thylakoid phosphoproteins are indicated. (B) The autoradiogram of 32P-labeled proteins released from the membranes during illumination of thylakoids for the times indicated above the lanes. (C) Coomassie-stained gel of the proteins released from phosphorylated thylakoid membranes by washing with 2 M NaBr. The position of the TSP9 double band is indicated.
