title: [Dehydrogenases of alpha-keto acids from pigeon breast muscle].
abstract: The structure, function and regulation of pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase complexes from pigeon breast muscle are reviewed. The nature of essential groups involved in the formation of active centers of the first components of the complexes, i.e., pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase, is described. The catalytic mechanism of the pyruvate dehydrogenase reaction and the peculiarities of cooperative interactions of the active centers of the above enzymes are discussed.
