20100009418 | Increasing NADPH-Dependent Products - A method of increasing cellular NADPH levels by expressing one or more genes that encode an enzyme that causes the production of NADPH. The system is combined with other enzymes that require NADPH, thus improving the overall yield of the desired product. | 01-14-2010 |
20100009403 | Reduced Activity of Ubica in E. Coli - Production of products by engineered bacteria is increased by regulating cellular respiration. Cellular respiration is controlled by reducing electron transfer enzyme activity. Some examples of electron transfer enzymes include NADH dehydrogenases, Succinate dehydrogenases, ubiquinone synthesis, cytochrome O, and cytochrome D. In one example, deletion of UbiCA prevents respiration. Respiration can the be controlled by addition of ubiquinone or expression of ubiCA. | 01-14-2010 |
