Adaptive immunity is acquired when foreign substances enter the body. Interestingly, this immune system exists not only higher organisms but also many bacteria. The CRISPR-Cas systems are the bacterial adaptive immune systems against foreign DNA and RNA derived from phages or plasmids. Many bacteria can memorize the sequences of foreign DNA and RNA, and remove them by means of these systems. Structural and functional studies of these systems have dramatically progressed over the past few years. In particular, one of the CRISPR-Cas systems, Cas9, has received considerable attention as a highly efficient tool for genome editing.

The final goal of this research project is the understanding of all fundamental biological phenomena in terms of physical chemistry. As a model organism for the structural and functional studies, an extremely thermophilic bacterium, Thermus thermophilus HB8, is very promising because of the small genome size, the availability of genetic tools for functional analysis, and the thermostability of its proteins (http: //www.thermus.org/) . In this report, we summarize the recent progress of this research project toward the systems biology.
