A plastocyanin from the cyanobacterium Synechococcus sp. PCC 7942 has been crystallized in two different forms by hanging-drop vapour diffusion with ammonium sulfate as precipitant. Form I is hexagonal, space group P61 or P65, with unit-cell dimensions a = b = 34.62 and c = 107.22 A. Form II is tetragonal, space group P41 or P43, with unit-cell dimensions a = b = 43.05 and c = 56.94 A. Form I crystals diffract to 2.5 A using graphite-monochromated Cu Kalpha radiation from a Rigaku RU-300 rotating-anode generator operated at 40 kV and 100 mA. Form II crystals diffract to 1.9 A using synchrotron radiation at beamline BL6A of the Photon Factory (KEK). Molecular-replacement calculations using the structure of plastocyanin from Ulva pertusa have been performed.
