Kinase replacement by a dehydrogenase for Escherichia coli glycerol utilization

A mutant of Escherichia coli that employs a glycerol:nicotinamide adenine dinucleotide 2-oxidoreductase (EC 1.1.1.6), instead of adenosine 5'-triphosphate:glycerol 3-phosphotransferase (EC 2.7.1.30), as the first enzyme for the dissimilation of glycerol was constructed. This mutant, like the wild-type strain, still cannot grow anaerobically on glycerol without an exogenous hydrogen acceptor.
