1.2.4.1	asymmetric reconstruction of the active, native pyruvate dehydrogenase complex by cryo-EM as a dynamic assembly. Enzyme clusters form a transient catalytic nanocompartment. The flexible parts of the dehydrogenase factory are notably restricted by a density cloud surrounding single E1p and E3 subunits. This density cloud presumably is composed of E1p and E3. The E1p and E3 proteins are not observed to interact directly with the E2p core but are spatially confined in relative proximity	762891	
1.2.4.1	full and dynamic structural model of full human pyruvate dehydrogenase complex, including binding of the linking arms to the surrounding E1 (pyruvate decarboxylase) and E3 (dihydrolipoamide dehydrogenase) enzymes via their binding domains with variable stoichiometries. An optimalsetting of approximately 30 copies of E1 ensures stability of the surrounding E1 and E3 clouds. Decreasing the number of E1s increases the flexibility of the now nonoccupied arms. Their flexibility depends on the presence of other E1s and E3s in the vicinity, even if they are associated with other arms. As one consequence, the radius of gyration decreases with decreasing number of E1s	763312	
1.2.4.1	homology modeling and docking of inhibitor N-((1-((4-amino-2-methylpyrimidin-5-yl)methyl)-5-iodo-1H-1,2,3-triazol-4-yl)methyl)-4-nitrobenzenesulfonamide. The compound can inhibit PDH subunit E1 by occupying the thiamin diphosphate-binding pocket and then blocking PDH E1 bound to thiamin diphosphate as competitive inhibitor	762797	
1.2.4.1	in complex with phosphonolactylthiamine diphosphate as structural and electrostatic analogue of alpha-lactylthiamin diphosphate. Presence of phosphonolactylthiamin diphosphate causes large conformational changes	674563	
1.2.4.1	modeling of the beta-subunit of the pyruvate decarboxylase component of the pyruvate dehydrogenase complex based on the crystal structures of the homologous 2-oxoisovalerate decarboxylase of Pseudomonas putida and Homo sapiens. The negatively charged side chain of Glu285 and the hydrophobic side chain of Phe324 are of particular importance in the interaction with the peripheral subunit-binding domain of the dihydrolipoyl acetyltransferase component of the complex	736099
