Mitochondrial protein kinases (mPKs) are molecular switches that, down-regulate the oxidation of branched-chain alpha-ketoacids and, pyruvate. Elevated levels of these metabolites are implicated in disease, states such as insulin-resistant Type II diabetes, branched-chain, ketoaciduria, and primary lactic acidosis. We report a three-dimensional, structure of a member of the mPK family, rat branched-chain alpha-ketoacid, dehydrogenase kinase (BCK). BCK features a characteristic, nucleotide-binding domain and a four-helix bundle domain. These two, domains are reminiscent of modules found in protein histidine kinases, (PHKs), which are involved in two-component signal transduction systems., Unlike PHKs, BCK dimerizes through direct interaction of two opposing, nucleotide-binding domains. ...

== Function ==
 +
[https://www.uniprot.org/uniprot/BCKD_RAT BCKD_RAT] Catalyzes the phosphorylation and inactivation of the branched-chain alpha-ketoacid dehydrogenase complex, the key regulatory enzyme of the valine, leucine and isoleucine catabolic pathways. Key enzyme that regulate the activity state of the BCKD complex.
