Outline of Final Research Achievements

In this work we have developed holo-abzyme in which the antigen-combining site can bind the artificial cofactors which have functional groups for the catalysis. The holo-abzyme catalyzes various types of chemical transformations by simply exchanging the artificial cofactors. We also succeeded in the X-ray crystal analysis of holo-abzyme 27C1, showing the molecular basis of the catalysis by 27C1.
