In praise of impurity: 30S ribosomal S15 protein-assisted crystallization of turnip yellow mosaic virus proteinase

Diffraction-quality crystals of the turnip yellow mosaic virus proteinase/ubiquitin hydrolase could only be obtained from a protein preparation that was heavily contaminated with E. coli 30S ribosomal S15 protein. Crystal packing reveals the basis of this observation.

Crystallization and preliminary X-ray analysis of Chandipura virus glycoprotein G

Chandipura virus glycoprotein ectodomain (Gth) was purified and crystallized at pH 7.5. X-ray diffraction data set was collected to a resolution of 3.1 Å.
