title: Expression, purification, crystallization and preliminary X-ray diffraction studies of triosephosphate isomerase from methicillin-resistant Staphylococcus aureus (MRSA252).
abstract: Triosephosphate isomerase from methicillin-resistant Staphylococcus aureus (MRSA252) was cloned in pQE30 vector, overexpressed in Escherichia coli M15 (pREP4) cells and purified to homogeneity. The protein was crystallized from 1.6 M trisodium citrate dihydrate pH 6.5 using the hanging-drop vapour-diffusion method. The crystals belonged to space group P4(3)2(1)2, with unit-cell parameters a = b = 79.15, c = 174.27 A. X-ray diffraction data were collected and processed to a maximum resolution of 1.9 A. The presence of two molecules in the asymmetric unit gave a Matthews coefficient (V(M)) of 2.64 A(3) Da(-1), with a solvent content of 53.63%.
