Expression, purification, crystallization and preliminary crystallographic analysis of the calponin-homology domain of Rng2.
Rng2 is a multidomain protein component of the actiomyosin ring and the spindle pole body necessary for cytokinesis in Schizosaccharomyces pombe. The calponin-homology domain of Rng2 from S. pombe has been overexpressed, purified and crystallized. The crystals belong to space group P2(1). Br- and Hg-derivative data sets were measured to 2.21 A using synchrotron radiation from crystals that were partially fixed with glutaraldehyde. Electron-density maps have been obtained from two-wavelength MAD on the Br derivative and SAD on the Hg derivative.
