Crystal Structure of ‘Gammexane' [PDF]

Nature, 1948
THE crystal structure of γ-benzenehexachloride, the insecticide ‘Gammexane', has been determined by X-ray analysis (Weissenberg diagram) in the usual way of trial and error, starting from Patterson data and supported by repeated Fourier syntheses. Cell dimensions: a = 8·5 A.; b = 10·3 A.; c = 13·9 A. ; β = 121°.

The crystal structure of cyclin A [PDF]

Structure, 1995
Eukaryotic cell cycle progression is regulated by cyclin dependent protein kinases (CDKs) whose activity is regulated by association with cyclins and by reversible phosphorylation. Cyclins also determine the subcellular location and substrate specificity of CDKs.
