PCC 7942.\nA 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.","tracks":[{"project":"CyanoBase","denotations":[{"id":"T1","span":{"begin":50,"end":62},"obj":"protein"},{"id":"T2","span":{"begin":113,"end":125},"obj":"protein"}],"attributes":[{"subj":"T1","pred":"source","obj":"CyanoBase"},{"subj":"T2","pred":"source","obj":"CyanoBase"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"CyanoBase","color":"#ec93e4","default":true}]}]}}
