Biography & Introduction

The main interest study is to use small, soluble protein scaffold, and the genetic incorporation of unnatural amino acid to design easy-to-characterize, easy-to-produce, and easy-to-optimize metalloenzymes which catalyze these important reactions with equal or greater efficiency/selectivity than that of the natural systems. A series of studies of themetalloenzymes analog has been studied based on the genetic encodingtechnology. For the first time we have successfully designed a functional cytochrome c oxidase model that catalyzes selective and efficient oxygen reduction to water with the 18 kD myoglobin. Second, through the incorporation of metal-chelating amino acids into green fluorescent protein, photoinduced electron transfer was shown to occur within one nanosecond in a distance dependent manner. Such compounds can be used as power tools for studying of PET and using of biological components to achieve efficient and controllable light-induced charge separation.
