An extremely simple biomimetic oxidation system, consisting of mixing metal complexes of amphiphilic corroles with serum albumins, utilizes hydrogen peroxide for asymmetric sulfoxidation in up to 74% ee. The albumin-conjugated manganese corroles also display catalase-like activity, and mechanistic evidence points toward oxidant-coordinated manganese(III) as the prime reaction intermediate.

Oxidation of thioanisoles, catalyzed by chiral manganese(III) and iron(III) corroles, provides the corresponding sulfoxides in moderate chemical yields and low enantioselectivities. Biocatalysis by non-chiral albumin-associated manganese(III) corroles proceeds much better and allows for the enantioselective synthesis of the pharmacologically important R-modafinil, in 88% yield and 73% ee.

[FeFe]-Hydrogenases are hydrogen producing metalloenzymes with excellent catalytic capacities, highly relevant in the context of a future hydrogen economy. Here we demonstrate the synthetic activation of a heterologously expressed [FeFe]-hydrogenase in living cells of Synechocystis PCC 6803, a photoautotrophic microbial chassis with high potential for biotechnological energy applications. H2-Evolution assays clearly show that the non-native, semi-synthetic enzyme links to the native metabolism in living cells.

Light induced enantioselective oxidation of an organic molecule with water as the oxygen atom source is demonstrated in a system where chirality is induced by a protein, oxygen atom transfer by a manganese corrole, and photocatalysis by ruthenium complexes.

Hydrogenases are gas processing redox enzymes central in hydrogen metabolism. The interdisciplinary nature of hydrogenase research is underscored by the development of “artificial maturation”, enabling the preparation of semi-synthetic hydrogenases through the incorporation of synthetic cofactors into a range of apo-hydrogenase hosts under in vitro and in vivo conditions. Herein, we discuss how the preparation of such semi-synthetic [FeFe]-hydrogenases has elucidated structural elements of the cofactor critical for catalysis and reactivity towards known inhibitors. It has also provided a convenient method for exploring the biodiversity of this enzyme family and thereby facilitated investigation of the role of the outer-coordination sphere in tuning the reactivity of the H-cluster. In parallel, hijacking the assembly line of the [FeFe]-hydrogenase through incorporation of synthetic precursors has provided detailed insight into the biosynthesis of the H-cluster. Moreover, it has allowed the preparation of Mn analogs of [Fe] hydrogenase.
