Artificial metalloenzymes for enantioselective catalysis.
Artificial metalloenzymes have emerged over the last decades as an attractive approach towards combining homogeneous catalysis and biocatalysis. A wide variety of catalytic transformations have been established by artificial metalloenzymes, thus establishing proof of concept. The field is now slowly transforming to take on new challenges. These include novel designs, novel catalytic reactions, ...
متن کاملLipase active site covalent anchoring of Rh(NHC) catalysts: towards chemoselective artificial metalloenzymes.
A Rh(NHC) phosphonate complex reacts with the lipases cutinase and Candida antarctica lipase B resulting in the first (soluble) artificial metalloenzymes formed by covalent active site-directed hybridization. When compared to unsupported complexes, these new robust hybrids show enhanced chemoselectivity in the (competitive) hydrogenation of olefins over ketones.
متن کاملCatalyst design in oxidation chemistry; from KMnO4 to artificial metalloenzymes.
Oxidation reactions are an important part of the synthetic organic chemist's toolkit and continued advancements have, in many cases, resulted in high yields and selectivities. This review aims to give an overview of the current state-of-the-art in oxygenation reactions using both chemical and enzymatic processes, the design principles applied to date and a possible future in the direction of hy...
متن کاملArtificial metalloenzymes for enantioselective catalysis: recent advances.
Catalysis is the most efficient strategy for the preparation of enantiopure products. Homogeneous and enzymatic catalyses are in many respects complementary in terms of substrate and reaction scope, operating conditions, enantioselection mechanism, etc. In terms of performance optimization, directed evolution methodologies outperform combinatorial ligand libraries. With the aim of combining the...
متن کامل5. Directed evolution of artificial metalloenzymes: bridging synthetic chemistry and biology
Directed evolution is a powerful algorithm for engineering proteins to have novel and useful properties. However, we do not yet fully understand the characteristics of an evolvable system. In this chapter, we present examples where directed evolution has been used to enhance the performance of metalloenzymes, focusing first on ‘classical’ cases such as improving enzyme stability or expanding th...
