title: An inducible phosphoenolpyruvate: dihydroxyacetone phosphotransferase system in Escherichia coli.
abstract: A phosphoenolpyruvate: dihydroxyacetone phosphotransferase was induced in Escherichia coli grown on dihydroxyacetone as sole carbon source or in its presence. This is the first example of a triose which can be acted upon by the membrane complex to provide a central intermediate in glycolysis. The presence of this system explains the ability of a mutant, in which the ATP-dependent glycerol kinase is genetically replaced by a glycerol: NAD 2-oxidoreductase, to grow on glycerol.
