ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	5.5	298	Crystals were grown from one part RtcB solution at 200 micromolar, mixed with one part reservoir solution, 2.1 M ammonium sulfate, 0.1 M bistris buffer. Crystals were cryoprotected in reservoir solution supplemented with 20% sucrose., pH 5.5, VAPOR DIFFUSION, HANGING DROP, temperature 298K
