1VAPOR DIFFUSION, HANGING DROP5.5291PrfA was co-crystallized with complex 1 (5 mol excess). Crystals grew in 5 days after 1 microL of the protein solution (3.5 mg per ml PrfA, 200 mM NaCl, 20 mM NaP buffer, pH 6.5) was mixed with an equal volume of precipitant solution containing 20% PEG-4000, 16% isopropanol, 100 mM Na citrate pH 5.5 and allowed to equilibrate over a 1 ml solution of the precipitant in a Linbro plate. Before data collection, the crystals were transferred to a cryo-protectant solution including 16% glycerol in the precipitant solution.
