Crystallization and preliminary crystallographic study of cucurmosin, a ribosome-inactivating protein from the sarcocarp of Cucurbita moschata

Cucurmosin, a ribosome-inactivating protein purified from pumpkin, the sarcocarp of Cucurbita moschata, has been crystallized using polyethylene glycol as a precipitant. The crystals belong to space group P2₁2₁2₁ and have unit-cell parameters a = 41.91, b = 59.48, c = 98.78 Å. There is one molecule in the asymmetric unit. The diffraction data to 3.0 Å resolution were collected on a MAR Research image-plate detector.
