Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of YvoA from Bacillus subtilis

The putative transcriptional regulator protein YvoA (BSU35030) from Bacillus subtilis was cloned and heterologously expressed in Escherichia coli. The protein was purified by immobilized metal-affinity chromatography and size-exclusion chromatography and subsequently crystallized. A complete native data set was collected to 2.50 angstrom resolution. The crystals belonged to the monoclinic space group C2 and preliminary analysis of the diffraction data indicated the presence of approximately 12 molecules per asymmetric unit.
