Roles of LipA in PSII complexes in vitro. Purified PSII monomers and dimers (corresponding to 10 μg chlorophyll) were incubated with recombinant LipA protein (5 μg proteins) at 32°C for 10 min, and PSII complexes (A) and lipid contents (B) were analyzed by BN-PAGE and high-performance liquid chromatography-evaporative light scattering detector system, respectively. D, dimer; M, monomer; and RC47, CP43-less monomer. Values for level of PSII-D are mean ± sd of results from three independent experiments. Asterisks indicate statistically significant differences between WT and lipA cells (P < 0.01, Student’s t test).
