pubmed:abstractText |
A cDNA fragment containing the Pisum sativum GapN gene, which encodes the non-phosphorylating glyceraldehyde-3-phosphate dehydrogenase, was cloned in a prokaryote expression vector. This construct enabled Escherichia coli strain W3CG, a mutant which lacks the glycolytic phosphorylating G3P dehydrogenase, to grow aerobically on sugars. The functionally complemented mutant exhibited high levels of the catalytically active plant enzyme, which renders 3-phosphoglycerate and NADPH, thus bypassing the first substrate level phosphorylation step of the glycolysis. As expected if such a glycolytic bypass would be operative in vivo, this clone failed to grow anaerobically on sugars in contrast to W3CG clones complemented with phosphorylating glyceraldehyde-3-phosphate dehydrogenases. According to the irreversible catabolic character of the non-phosphorylating reaction, the GapN-complemented clone was unable to grow on gluconeogenic substrates. This metabolic engineering approach demonstrates that a pure catabolic Embden-Meyerhof pathway with no net energy yield is feasible.
