Crystallization and preliminary X-ray diffraction studies of glycerol 3-phosphate cytidylyltransferase from Staphylococcus aureus

Glycerol 3-phosphate cytidylyltransferase from Staphylococcus aureus (TarD(Sa)) has been expressed in Escherichia coli, purified to homogeneity and crystallized. The strategy used for determining crystallization conditions employed hanging-drop sparse-matrix screens and required a combination of three different optimization approaches. Specifically, the presence or absence of cofactors needed to be surveyed, the effects of small-molecule …
