X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	5.5	291	PROTEIN WAS CRYSTALLIZED FROM 25 percent PEG 3350, 20 MM SODIUM CITRATE, PH 5.5. Alanyl-5'-O-adenosine phosphoramidate soaking was achieved as follows. 1 uL of a stock solution of 100 mM ligand was added to 2uL of reservoir solution, to achieve a concentration of ~35mM in the soaking solution. A few RNase A crystals were soaked for 120 - 130 minutes in the soaking solution.
