A highly efficient and chemoselective biphasic hydroformylation of olefins was accomplished using water soluble complexes formed by the interaction between Rh(CO)2(acac) and human serum albumin (HSA), a readily available water soluble protein. A new type of shape-selectivity was observed in the hydroformylation of sterically hindered olefins.

The preparation of a heterogeneous bifunctional catalytic system, combining the catalytic properties of an organometallic catalyst (racemization) with those of an enzyme (enantioselective acylation) is described. A novel ruthenium phosphonate inhibitor was synthesized and covalently anchored to a lipase immobilized on a solid support (CALB, Novozym® 435). The immobilized bifunctional catalytic system showed activity in both racemization of (S)-1-phenylethanol and selective acylation of 1-phenylethanol.

Organic synthesis using biocatalysts has been developed over many years and is still a prominent area of research. In this context, various hybrid biocatalysts composed of a synthetic metal complex catalyst and a protein scaffold (i.e. artificial metalloenzymes) have been constructed. One of the most recent research areas in biocatalysts-mediated synthesis is CC bond/cleavage, the most important type of reaction in organic chemistry. Some of the artificial enzymes were applied to in-cell reactions as well as in vitro systems. The effects of the structural fluctuation in biomacromolecules on their functions have also been realized. This review article includes recent research examples of artificial metalloenzymes used to CC bond formation/cleavage. As a perspective, we also focus on how we apply protein dynamics factor for the creation of new generation artificial metalloenzymes.

The synthesis of a new cationic iron metalloporphyrin–estradiol conjugate is reported. After a study of its association with the anti-estradiol antibody 7A3 by UV–visible spectroscopy, the influence of the antibody on the sulfoxidation of thioanisole by H2O2 catalyzed by the iron–metalloporphyrin has been investigated.
