Crystallization and preliminary crystallographic study of cathepsin D inhibitor from potatoes

J Mol Biol. 1991 Mar 5;218(1):21-2. doi: 10.1016/0022-2836(91)90869-8.

Abstract

Single crystals of the glycosylated inhibitor of cathepsin D and trypsin isolated from potato tubers were obtained using the hanging drop vapor diffusion method and ammonium nitrate as precipitant. The crystals exhibit strong F222 pseudo symmetry but belong to the orthorhombic space group C222 or C222(1), with cell parameters a = 73.8 A, b = 119.9 A and c = 133.2 A with two molecules per asymmetric unit. The crystals diffract to a resolution of 2.4 A.
