FunctionPLAS_PHOLA Participates in electron transfer between P700 and the cytochrome b6-f complex in photosystem I. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe beta-sandwich cupredoxin Plastocyanin (Pc) was found to self-assemble in the presence of Zn(2+), a known mediator of protein-protein interfaces. Diffraction-quality crystals of Pc grew from solutions containing zinc acetate as the sole precipitant. Di- and trinuclear zinc sites contribute to the crystal contacts in this structure. A different crystal form, also involving numerous zinc bridging ions, was obtained in the presence of poly(ethylene glycol) 8 000. Comparison of the two crystal forms reveals the effect of macromolecular crowding on self-assembly. Solution-state structural characterisation of the Zn(2+)-mediated Pc oligomers was performed by using a combination of chemical shift perturbation mapping and small-angle X-ray scattering. The data indicate the formation of dimers in solution. The implications for metal-mediated assembly and crystallisation are discussed.
