title: Overexpression, purification, crystallization and preliminary X-ray analysis of uracil N-glycosylase from Mycobacterium tuberculosis in complex with a proteinaceous inhibitor.
abstract: Uracil N-glycosylase is an enzyme which initiates the pathway of uracil-excision repair of DNA. The enzyme from Mycobacterium tuberculosis was co-expressed with a proteinaceous inhibitor from Bacillus subtilis phage and was crystallized in monoclinic space group C2, with unit-cell parameters a = 201.14, b = 64.27, c = 203.68 A, beta = 109.7 degrees. X-ray data from the crystal have been collected for structure analysis.
