We design and create functional molecules on protein structure format. Proteins are the first functional molecules that are made by following the genetic information. Huge sequence variation of 20 kinds of amino acids can express different molecules the number of which is more than the total number of stars, and by utilizing these structures, we create the functional molecules that can be utilized in the fields of medicine, environment and nanotechnology.

Generating new functional proteins can be mimicked in vitro (molecular evolutional technique). This methodology enables us to create molecules with the functions of one's own desiring, and recent trend of medicine in pharmaceuticals is shifting from low organic molecules t to biotechnology-based medicine such as proteins. Especially with regards to molecular targeted drugs that demonstrate efficacy only on a specific region of the body, proteins are considered to be promising molecular species. In the environmental field, enzyme proteins can degrade biomass resources to sugar without adding heat and acid, from which yeast can produce ethanol. Generation of highly functional enzymes are being conducted worldwide. Concerning the expansion into nanotechnology, even smaller devices with complex functions are beginning to be developed. We have succeeded in being the first in the world to create antibody proteins that can specifically bind to nano-sized material particles by utilizing the function of antibody proteins that can specifically bind to bacteria and viruses. The antibody protein can act as the "glue in the nanoworld."

Various proteins have come into existence since life first appeared, and 10,000 proteins are reported a year. This database and the evolutionary technique make proteins unique and they are not found for other molecules. In addition to medicine and environment, we would like to venture boldly into other fields which have not utilized proteins up until now through these database and technology.
