摘要：

Glyceraldehyde-3-phosphate dehydrogenase 1 (GAP1) from methicillin-resistant Staphylococcus aureus (MRSA252) has been purified to homogeneity in the apo form. The protein was crystallized using the hanging-drop vapour-diffusion method. The crystals belonged to space group P2(1), with unit-cell parameters a = 69.95, b = 93.68, c = 89.05 angstrom, beta = 106.84 degrees. X-ray diffraction data have been collected and processed to a maximum resolution of 2.2 angstrom. The presence of one tetramer in the asymmetric unit gives a Matthews coefficient (V-M) of 1.81 angstrom(3) Da(-1) with a solvent content of 32%. The structure has been solved by molecular replacement and structure refinement is now in progress.
