Research Abstract

We have isolated one of the monomeric subunits as well as the hexameric assembly of swimming crab Portunus trituberculatus and attempted to convert them to monooxygenase by applying the above-mentioned sysetm. We also tried to develop a metallo-β-lactamase to construct a new artificial dinuclear metalloenzymes as a metal-binding platform.
