[Amino acid composition of the alpha-ketoglutarate dehydrogenase from the breast muscle of the pigeon].

The amino acid composition of alpha-ketoglutarate dehydrogenase--a component of alpha-ketoglutarate dehydrogenase complex--from the pigeon breast muscle has been determined. A significant similarity of the enzyme amino acid composition isolated from systematically remote species has been revealed by comparison of the data obtained with the literary one concerning the alpha-ketoglutarate dehydrogenase from Escherichia coli and pig heart.
