Transcription factor Rv0081 from Mycobacterium tuberculosis: purification, crystallization and initial crystallographic analysis.

ABSTRACT: Because of its high infectivity and pathogenicity, Mycobacterium tuberculosis is a serious threat to human health. While the transcription-regulatory system of M. tuberculosis remains incompletely understood, Rv0081, an essential regulatory hub, is known to mediate the initial response to hypoxia in the long-term survival of M. tuberculosis. Here, the production, crystallization and initial X-ray crystallographic analysis of Rv0081 are reported. The crystals of Rv0081 belonged to space group P6₂, with unit-cell parameters a = 67.48, b = 67.48, c = 40.84 Å, γ = 120°. The Matthews coefficient is 2.09 ų Da^-1, assuming the presence of one molecule in the asymmetric unit, with a corresponding solvent content of 41.27%. Phasing of the native crystal form of Rv00
