    The crystallization of the higher plant similar to 1 gigadalton homodimeric lipid-pigment-protein complex of photosystem II constitutes a challenging undertaking that has not been crowned with success to date. In the continuation of our previous efforts (Kuta-Smatanova et al. Photosyn. Res. 2006, 90, 255-259) that had provided needle and plate crystals of plant photosystem II for the first time, we report on a study to crystallize three-dimensional crystals of the photosystem 11 from Pisum sativum L. suitable for X-ray analysis. In our screening, we optimized temperature, supersaturation rate, and concentrations of detergents, buffers, salts, and organic additives. We used a sitting and hanging drop vapor-diffusion method, microbatch under oil and counter-diffusion techniques, and direct and cross-influenced procedures. We have identified that the major limiting factors for the growth of crystals are the photosystem II stability and requirement of indispensable divalent cations.
