crystallization communications
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.
structural communications
The structure of the Rem2 G domain bound to GDP is reported in a monoclinic crystal form at 2.66 Å resolution.
