Outline of Final Research Achievements

A shellfish carbonic anhydrase having Ca2+-binding site has a relation to the formation of shell that has CaCO3 as a principal component. If the manner concerning the shell formation can be appropriately mimicked, it is possible to develop a critical method, in which CO2 is efficiently converted into CaCO3 crystal where ubiquitous calcium ions are seen, in the CO2 capture and storage (CCS) technology. In this study, we are focusing on three characters of the CA enzyme: 1) the specificity to a low concentration of CO2, 2) the high ability of CO2 hydration, and 3) the Ca2+ binding affinity, to construct a catalytic module.
