Abstract:
The gene product of open reading frame Rv3117 from Mycobacterium tuberculosis (Mtb) strain H37Rv is annotated as encoding a probable rhodanese-like thiosulfate sulfurtransferase (MtbCysA3). MtbCysA3 was expressed and purified and then crystallized using the sitting-drop vapour-diffusion method. X-ray diffraction data were collected and processed to a maximum resolution of 2.5 A. The crystals belong to the monoclinic space group P2(1), with unit-cell parameters a = 38.86, b = 91.43, c = 83.57 A, beta = 96.6 degrees . Preliminary diffraction data shows that two molecules are present in the asymmetric unit; this corresponds to a V(M) of 2.4 A(3) Da(-1).
