Binding protein-dependent transports in 2-oxo acids dehydrogenase mutants of Escherichia coli

The binding protein-dependent transport of ribose, galactose and maltose are reduced in several 2-oxo acids dehydrogenase mutants of Escherichia coli. The results suggest an implication of the pyruvate dehydrogenase complex and to a lesser extent of the 2-oxoglutarate dehydrogenase complex in the energization of these transport systems.
