Escherichia coli stress protein YciF: expression, crystallization and preliminary crystallographic analysis

Acta Crystallogr D Biol Crystallogr. 2004 Dec;60(Pt 12 Pt 2):2389-90. doi: 10.1107/S0907444904028227. Epub 2004 Nov 26.

Abstract

The Escherichia coli stress protein YciF was overexpressed and purified by three chromatographic steps. Crystals were obtained using ammonium sulfate as a precipitant. The YciF protein crystals diffracted beyond 2.25 A resolution using a rotating-anode X-ray source. The lattice type is rhombohedral, with unit-cell parameters a = b = 80.0, c = 131.03 A, alpha = beta = 90.0, gamma = 120.0 degrees. The crystal belongs to space group R32.
