Each of the twelve enzymes for glycolytic fermentation, eleven from Escherichia coli and one from Saccharomyces cerevisiae, have been over-expressed in E. coli and purified with His-tags. Simple assays have been developed for each enzyme and they have been assembled for fermentation of glucose to ethanol. Phosphorus-31 NMR revealed that this in vitro reaction accumulates fructose 1,6-bisphosphate while recycling the cofactors NAD+ and ATP. This reaction represents a defined ATP-regeneration...[Show more]
