The SARS-3CLpro:47 a inhibitor complex were co-crystallized using the hanging-drop, vapor-diffusion method by setting up 3 uL drops that were formed by adding 1 uL of purified SARS-3CLpro (10 mg/mL) that had been incubated for three hours with a 3 molar excess of the of compound 47, and 2 uL of reservoir solution: 3 mM DTT, 50 mM MES pH 6.0, 40 mM KCl, 1% MPD, and 5% PEG-10K. Protein crystallization plates were set up at 4 C and protein crystals appeared 24 hours after setting up crystallization plates. Crystals were harvested with a nylon loop and then quickly swiped through the same mother-liquor solution supplemented with 15% MPD. |
