Abstract
Free methionine-(R)-sulfoxide reductase (fRMsr) catalyzes the reduction of the free form of methionine-(R)-sulfoxide back to free methionine. The fRMsr protein from Staphylococcus aureus was overexpressed in Escherichia coli, purified and crystallized at 295 K using ammonium sulfate as a precipitant. Diffraction data were collected to 1.7 Å resolution from a native crystal using synchrotron radiation. The crystal belonged to the hexagonal space group P6122, with unit-cell parameters a = b = 89.84, c = 88.75 Å, = β = 90, = 120°. Assuming the presence of one molecule in the asymmetric unit, the calculated Matthews coefficient value was 2.21 Å3 Da -1, with a solvent content of 57.1%.
