A dimeric form of acetylcholinesterase from Torpedo californica was purified to homogeneity by affinity chromatography subsequent to solubilization with a phosphatidylinositol-specific phospholipase C of bacterial origin. Bipyramidal crystals of the enzyme were obtained from solutions in polyethylene glycol 200. The crystals diffract to 2.0 A (1 A = 0.1 nm) resolution. They were found to be orthorhombic, space group P2221, with a = 163.4(+/- 0.2) A, b = 112.1(+/- 0.2) A, c = 81.3(+/- 0.1) A.
