ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP		291	AtNATA229-226 was concentrated to 10 mg/ml and incubated with a fivefold molar excess of CoA for 18 h on ice. Crystallization drops contained 200 nl protein solution and 200 nl precipitant solution. Crystals appeared within 2-18 hours in several conditions. The best diffracting crystals were obtained from the precipitant condition with 0.1 M sodium citrate (pH 5.5), 0.2 M lithium sulfate and 15 % (v/v) ethanol. Crystals were cryo-protected with 20 % glycerol and flash-frozen in liquid nitrogen.
