Abstract:Cucurmosin 2, a type 1 ribosome-inactivating protein (RIP) isolated from sar-cocarp of Cucurbita moschata, has been crystallized by the vapor-diffusion method using PEG6000 as the precipitant. The crystals belong to the orthorhombic space group P212121, with unit cell parameters a = 55.853, b = 65.507, c = 91.754 A, and have one molecule per asymmetric unit. X-ray data have been collected to 1.8 A using a synchrotron source.
Keywords:ribosome-inactivating protein  Cucurbita moschata  crystallization
