Crystal structure of branched-chain alpha-ketoacid dehydrogenase kinase/S-alpha-chloroisocaproate complex with ADP

The structure was published by Tso, S.C., Chuang, J.L., Gui, W.J., Wynn, R.M., Li, J., and Chuang, D.T., in 2013 in a paper entitled "Structures of branched-chain alpha-ketoacid dehydrogenase kinase-inhibitor complexes" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.25 Å and deposited in 2011.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of [3-methyl-2-oxobutanoate dehydrogenase [lipoamide]] kinase, mitochondrial. This molecule has the UniProt identifier Q00972 (BCKD_RAT)search. The sample contained 418 residues which is 100% of the natural sequence. Out of 418 residues 310 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule has more than one probable quaternary state observed. For more details see the quaternary structure page.
