Crystal grow | Temperature: 278 K / Method: vapor diffusion, sitting drop / pH: 6 Details: The C2 crystal of halorhodopsin grew when a solution containing 3 mg/ml halorhodopsin, 0.4 % nonylglucoside, 1 M ammonium sulfate, 0.16 M sodium chloride, 0.04 M sodium citrate at pH 6 and 0. ...Details: The C2 crystal of halorhodopsin grew when a solution containing 3 mg/ml halorhodopsin, 0.4 % nonylglucoside, 1 M ammonium sulfate, 0.16 M sodium chloride, 0.04 M sodium citrate at pH 6 and 0.04 % sodium azide was concentrated by the vapor diffusion using a reservoir solution containing 2.8 M ammonium sulfate and 0.12 M sodium citrate at pH 6. For investigation of light-induced structural changes, the C2 crystal was soaked in a solution containing 0.1 M sodium bromide, 1.5 M trisodium citrate at pH 7 and 30 % trehalose. This crystal was illuminated at 240 K with orange light and cooled to 100 K at a rate of 2.3 K/sec in the dark., VAPOR DIFFUSION, SITTING DROP, temperature 278K |

THE OTHER THREE CHAINS (E F AND G) REPRESENT THE UNPHOTOLYZED STATES THAT CO-EXISTED IN THE ILLUMINATED CRYSTAL. THE ASYMMETRIC UNIT OF THE C2 CRYSTAL CONTAINS THREE SUBUNITS. THESE THREE SUBUNITS UNDERWENT DIFFERENT STRUCTURAL CHANGES WHEN THE CRYSTAL WAS ILLUMINATED AT 240K. THE C2 CRYSTAL HAD BEEN SOAKED IN 0.1M SODIUM BROMIDE, 1.5M TRISODIUM-CITRATE AT pH 7 AND 30% TREHALOSE. THE DIFFRACTION DATA WERE COLLECTED AFTER THE ILLUMINATED CRYSTAL WAS COOLED TO 100 K WITH A RATE 2.3K/SEC IN THE DARK.
