Abstract:
UDP-galactopyranose mutase (UGM) catalyzes the interconversion of UDP-galactopyranose and UDP-galactofuranose. A UGM-substrate complex from Deinococccus radiodurans has been expressed, purified and crystallized. Crystals were obtained by the microbatch-under-oil method at room temperature. The crystals diffracted to 2.36 A resolution at the Canadian Light Source. The space group was found to be P2(1)2(1)2(1), with unit-cell parameters a = 134.0, b = 176.6, c = 221.6 A. The initial structure solution was determined by molecular replacement using UGM from Mycobacterium tuberculosis (PDB code 1v0j) as a template model.
