研究领域

The cell is operating on multilayers of complexities to sustain its life cycle. The regulatory networks in the cell is complex in that the activities of cellular proteins are switched on and off by many types of posttranslational modifications such as phosphorylation, glycosylation and ubiquitination. The chemical transformations in the cell are also complex for the assembly of natural products of diverse structures through a myriad of biosynthetic pathways. The branch of chemical biology based on synthetic small molecules has provided inhibitors, activity-based probes, and imaging reagents to study cellular processes. However the complexities of the cell are far beyond the capacity of using small molecules to probe the biological mechanisms. We are thus developing another branch of chemical biology based on the “synthetic proteins” – engineered proteins with desired catalytic or binding properties, to investigate and manipulate the cellular processes. We have so far engineered the ubiquitin (UB) transfer cascade to map and reprogram signaling pathways mediated by protein ubiquitination. We have also engineered the natural product biosynthetic enzymes to harness the chemical transformations in the cell for the synthesis of drug molecules
