Crystallization and preliminary X-ray analysis of the hypothetical deaminase RPB_0146 from Rhodopseudomonas palustris HaA2.


ABSTRACT: RPB_0146, a putative deaminase from Rhodopseudomonas palustris HaA2, was expressed in Escherichia coli BL21 (DE3) cells and purified using a His6 tag by Ni2+-chelating affinity chromatography for X-ray crystallographic analysis. Diffraction-quality crystals were grown by the hanging-drop vapour-diffusion method at 289?K and diffracted to a resolution of 2.44?Å using a wavelength of 1.000?Å at the Photon Factory (KEK), Japan. The crystals belonged to the orthorhombic space group P2?2?2?, with unit-cell parameters a=66.26, b=123.94, c=155.95?Å.
