title: Crystallization and preliminary X-ray diffraction analysis of a plant ribonuclease from the seeds of the bitter gourd Momordica charantia.
abstract: Single crystals of ribonuclease Mc, a new class of plant ribonuclease from the seeds of the bitter gourd, were obtained from solutions of polyethylene glycol 8000 by the hanging-drop vapour diffusion method. The crystals belong to the orthorhombic space group P2(1)2(1)2(1) with cell dimensions a = 67.28 A, b = 75.21 A, c = 38.54 A. The assumption of one monomer per asymmetric unit gives rise to a Vm value of 2.29 A3/Da. The crystals diffract beyond 2.0 A resolution and are suitable for high resolution X-ray structure analysis.
