The research of Prof. dr. G.J. Poelarends is aimed at the discovery and design of novel biocatalysts and biosynthetic pathways for the production of pharmaceutically relevant products. One area of interest is the development of new biocatalysts and multienzymatic cascades for efficient asymmetric synthesis of noncanonical amino acids with biologically important properties. Another area of interest is the development of enantioselective biocatalysts for oxidation, reduction, hydration, Michael addition, hydroamination, and aldol addition reactions as broadly useful synthetic bond-forming methodologies for the production of pharmaceuticals and fine chemicals. Finally, we work on the characterization and optimization of promiscuous protein functions, which will contribute to expanding our knowledge of the parameters involved in natural and laboratory enzyme evolution.
