Engineering Photoenzymes for New-to-Nature Asymmetric Radical Processes

Project description

Light-driven enzymes for sustainable chemical synthesis

Chiral molecules are compounds that exist in two mirror-image forms like left and right hands. They are fundamental to many biological processes and widely used in pharmaceuticals, agriculture, and advanced materials. However, the high precision synthesis of chiral molecules remains a challenge. With the support of the Marie Skłodowska-Curie Actions programme, the PHOTO-BIO-ENG project aims to create innovative photoenzymes that utilise visible light to drive chemical reactions. These enzymes will enable the efficient, environmentally friendly production of complex chiral molecules under mild conditions. In collaboration with Johnson & Johnson, the project will demonstrate applications for biologically relevant compounds, advancing green chemistry and supporting next-generation drug and material development.

Objective

PHOTO-BIO-ENG aims to develop entirely new strategies for the stereoselective synthesis of complex chiral molecules. We will achieve this by combining biocatalysis and photocatalysis to generate photoenzymes for visible-light-driven radical processes. Utilizing directed evolution and high-throughput experimentation, we will create highly efficient and stereoselective photoenzymes capable of catalyzing transformations that are currently inaccessible to small-molecule catalysts and unachievable via ground-state thermal pathways. Our approach will use enzymes as green catalysts and visible light as a renewable energy source, with environmentally benign reaction conditions (ambient temperatures, aqueous solvents). By merging photochemical methodology with enzyme catalysis, we aim to demonstrate novel chemical transformations that produce chiral products with multiple stereocenters and excellent stereocontrol. This project will establish a highly effective and sustainable synthetic methodology, contributing to the advancement of green chemistry practices.

Collaboration with Johnson & Johnson will facilitate the development of photoenzymatic processes to yield chiral molecules with biologically relevant scaffolds. PHOTO-BIO-ENG combines the fellow’s experience in enzymatic catalysis and directed evolution with the host’s expertise in photo-triggered asymmetric radical processes. The interdisciplinary nature of the project will significantly enhance the fellow's expertise, providing comprehensive training and positioning them strongly for future career advancements.
