ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	7	291	JCSG+ C4: 10% (w/v) PEG 6K, 0.10 M HEPES pH 7.0, KlaeA.00020.b.B1.PW39167 at 17 mg/mL. Plate: 13125, well C4 drop 2. Puck: PSL-0714, Cryo: 20% PEG200 + 80% crystallant. 2mM NAD added prior to crystallization. The intensities were corrected for lattice translocation disorder which orginally caused high Rfactors (~25% and 29% for R and Rfree) and residual positive electron density throughout the polypeptide chains. The correction was based on major non-origin Patterson peaks, 1) (0.500, 0.027, 0.500) and its inverse (0.500, -0.027, 0.500) and 2) (0.000, 0.054, 0.000)
