2.3.1.12 crystal structure of pyruvate dehydrogenase kinase 2 bound to the inner lipoyl-bearing domain of dihydrolipoamide transacetylase is determined. Crystal structure reveals a pyruvate dehydrogenase kinase 2 dimer complexed with two inner lipoyl-bearing domains of dihydrolipoamide transacetylase. Comparison with apo-pyruvate dehydrogenase kinase 2 shows that dihydrolipoamide transacetylase binding causes rearrangements in PDHK2 structure that affect the dihydrolipoamidetransacetylase- and pyruvate dehydrogenase-binding sites 704423 2.3.1.12 E1p-E2p didomain subcomplex, sitting drop vapor diffusion method, using 20% (w/v) PEG 3350, 0.2% (w/v) NaN3, and 0.2 M ammonium tartrate dibasic buffer (pH 6.35) 736459 2.3.1.12 E2-E3 subcomplex of pyruvate dehydrogenase, E2: EC 2.3.1.12, E3: EC 1.8.1.4, various crystallization conditions 486199 2.3.1.12 E3 dimer with E2 and a small binding domain E2BD, hanging drop vapor diffusion method 486230 2.3.1.12 hanging drop vapor diffusion method 486228, 486236 2.3.1.12 His9-tagged catalytic domain, hanging drop vapor diffusion method, using 0.2 M potassium thiocyanate and 20% (w/v) polyethylene glycol 3350 736448 2.3.1.12 pyruvate dehydrogenase complex 94893
