Crystallization and preliminary X-ray crystallographic studies of a macromolecular antitumour antibiotic, C1027

C1027 is a macromolecular antitumour antibiotic produced by Streptomyces globispourus C1027 and consists of an apoprotein and a non-protein labile chromophore. The purified C1027 was monodisperse according to dynamic light-scattering measurements and crystallized in two different crystal forms from two different starting conditions using the vapour-diffusion method.

Crystallization and preliminary crystallographic studies on the chromo shadow domain (CSD) of mouse heterochromatin protein M31

The chromo shadow domain (CSD) of the murin HP1-like protein M31 has been crystallized and X-ray diffraction data have been collected to 2.9 Å. The native crystals belong to space group C222₁ with unit-cell parameters a = 60.0, b = 95.6, c = 91.7 Å and α = β = γ = 90°

Expression, crystallization and preliminary X-ray studies of the recombinant PTB domain of human dok-5 protein

The PTB domain of human dok-5 protein has been crystallized as well as a selenomethionmine-substituted protein for MAD phasing determination. The crystals belong to space group P3₂21 (a = b = 75.9, c = 108.0 Å) and diffract up to 2.3 Å resolution using synchrotron radiation.
