Outline of Final Research Achievements |
We tried to develop a method that arrange the order of multiple enzymes on DNA to construct artificial multienzyme complexes that catalyze sophisticated sequential or concerted reactions. To retain enzymes on DNA, we focused on a DNA sliding clamp. A stable DNA sliding clamp was discovered from a archaeon and then characterized. A DNA-binding protein was immobilized on DNA at the starting point of complex formation to avoid drop-off of proteins fused to the DNA sliding clamp. As as result, we successfully constructed multienzyme complexes on DNA.
