1	VAPOR DIFFUSION, SITTING DROP	5.5	291	Purified PrfA, in 200 mM NaCl and 20 mM NaP buffer at pH 6.5 was mixed with 1 mM IWP2 and 3.7 mM DTT prior to crystallization. Droplets of 1 microL protein solution at 3.1 mg ml-1 were mixed with 1 microL reservoir solution consisting of 29 % (w/v) PEG 4000, 100 mM sodium citrate pH 5.5, and 18 % (v/v) isopropanol. The dimethyl sulfoxide (DMSO) concentration was kept at 10% (v/v). Prior to vitrification, crystals were equilibrated for 2 days in a solution containing 35 % (w/v) PEG 4000, 100 mM sodium citrate pH 5.5 and 1 mM IWP-2.
