1.1.1.76 hanging drop vapor diffusion method with polyethylene glycol 4000 as precipitant 389579 1.1.1.76 hanging drop vapor diffusion method, using 17% (w/v) PEG 4000, 15% (v/v) glycerol and 1% (v/v) beta-mercaptoethanol in 100 mM MES buffer pH 6.4 737381 1.1.1.76 in complex with NAD+ and 2-mercaptoethanol, to 2.0 A resolution. The L-BDH subunit is composed of seven beta-strands, six alpha-helices and two short a helices, aFG1 and aFG2, which form a small lobe on top of the core domain. The conserved active site residues Asn112, Ser141, Tyr154 and Lys158 are located near the NAD+ molecule 712019 1.1.1.76 X-ray analysis 389579
