Outline of Final Research Achievements |
Protein dynamically fluctuates in solution and adopts various distinct conformations. However, the measurement of such conformational heterogeneity of protein is technically difficult and the determination of a conformational space of protein is challenging. So far, single molecule force measurement with optical tweezers is a promising technique to address it, but it is not easily applied to nucleic acid proteins because the single protein molecule is tethered by a DNA handle linker which may alter a conformational space of the captured nucleic acid protein. In this study we developed a novel method of single molecule force measurement, using polyethylene glycol as a handle for single molecule of nucleic acid proteins.
