title: Purification, crystallisation and preliminary X-ray diffraction study of ribosome inactivating protein: saporin.
abstract: We report here the crysallisation and molecular replacement results on the structure determination of S-9 isoform of the ribosome inactivating protein saporin. The protein was purified to homogeneity by a simple and efficient protocol. The crystals belong to the space group I4l with a = b = 91.47 A, c = 150.66 A and contain two molecules in the asymmetric unit.
