Structure of Arginyl-5'-O-adenosine phosphoramidate/RNase A
Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 1AFK
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 5.5 291 PROTEIN WAS CRYSTALLIZED FROM 25 percent PEG 3350, 20 MM SODIUM CITRATE, PH 5.5. Arginyl-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 ~33 mM in the soaking solution. A few RNase A crystals were soaked for 110 - 130 minutes in the soaking solution.
