Research | Current

The research of the Leung Research Group lies broadly at the interface between chemistry and biology. We aim to utilise our knowledge in protein structure and enzyme mechanism to help solve some of the world’s most urgent challenges. Our research is multidisciplinary, drawing on the fields of chemistry, biochemistry, biophysical chemistry, enzymology, molecular biology and structural biology.

Theme 1: Understanding disease mechanisms

Genetic disorders are associated with many serious and debilitating diseases. Our work aims to understand how genetic mutations may influence the structure and function of proteins and enzymes, establishing the relationship between molecular dysfunctions/dysregulations and the diseases that these mutations may cause.

● Chem. Commun. 2020, 56, 7857–7860.

Theme 2: Improving treatments and therapies

Infectious disease and antibiotic resistance are some of the biggest health challenges that the world are facing today. Our research tackles the underlying mechanisms that are important for the survival of bacteria, enabling new inhibition targets for the development of new antibiotic agents. 

● Drug Discov. Today 201924, 206–216.

Cancer is amongst the leading causes of death worldwide. We study molecular chaperones and DNA repair enzymes with an aim to develop new anti-cancer agents and chemosensitizers to overcome resistance and enhancing the effect of chemotherapy treatments.

● Int. J. Mol. Sci. 201920, 5333.

Theme 3: Improving agriculture to feed the world 

Despite soaring food cost and the growing world population, millions of tonnes of fresh produce are thrown out every year. We target plant enzymes with an aim to develop new chemical agents to regulate and control the ripening and browning processes of fruits and vegetables in order to reduce unnecessary waste of fresh produce.

● ChemistrySelect 20172, 10435–10441.

Theme 4: Improving methodologies in biochemical research

Protein-ligand interactions are fundamental to almost all biological processes in living organisms. Our laboratory specialises in the application of biophysical techniques, in particular NMR spectroscopy, to measure and quantify such interactions. We also conduct research to improve methodologies for the production and purification of recombinant proteins.
