Two crystal forms have been obtained by using ammonium sulfate as precipitant at different pH, one of which is single crystal. Diffraction data have been collected for the single crystal on a Mar Research 345 Image Plate. The analyses of the data show that the crystal can diffract to 0.28 nm resolution and belongs to the space group C2 with unit cell parameters a = 4.65 nm, b = 8.52 nm, c= 3.26 nm, α= γ= 90oooooooo, β= 110.5°. There are 2 molecules per asymmetric unit according to its unit cell volume and molecular weight.展开更多
