Biochemistry And Biophysics

Biochemistry and Biophysics

Major areas of focus are molecular microbiology related to infection and multi-drug resistance, plant biochemistry and biotechnology, and the replication, regulation and organisation of nucleic acids.

This focus brings together interdisciplinary expertise to address key biological questions across the scale range from atom to organism using single molecule fluorescence and confocal microscopy, structural biology (NMR spectroscopy and X-ray crystallography), and a variety of advanced biophysical, biochemical and cellular techniques.


Research in biochemistry and biophysics uses cutting edge molecular and biophysical techniques to address key challenges relevant to health and disease and biotechnology. Below are examples of how biochemistry and biophysics research has the potential to benefit society.

Impacting on health and disease

Bacterial antibiotic resistance and medical device infection

Mechanisms Of Antibiotic Resistance

Bacteria are able to form colonies – called biofilms – on implanted devices, which can lead to endocarditis, a bacterial infection of the heart. Biofilms help the bacteria to avoid  the immune system and antibiotics.  Prof. Jennifer Potts discovered unusual repetitive proteins that connect bacteria in biofilms. This discovery can lead to new treatments or ways to prevent biofilms forming.

Teaching bacteria to eat grass

Teaching bacteria to eat grass

The lignocellulosic components of plants have great potential to provide renewable feedstocks that can be fermented by bacteria to make high value chemicals and biofuels. Using methods of biochemistry and biophysics as well as microbiology and structural biology, the Thomas group are characterising the transporters and enzymes needed to create synthetic strains of bacteria that can degrade lignocellulose more efficiently and the Bruce group are discovering novel enzymes from composting that could also help in this process.

Examples of Biochemistry and Biophysics projects

DNA replication and genome stability. Each time a cell divides its genetic material must be copied accurately since mistakes can cause potentially life-threatening mutations. Using a combination of cutting-edge single-molecule biophysics, the Leake group is beginning to unravel the intricate mechanisms involved in genome stability. The McGlynn group exploits biochemistry, genetics and structural biology to understand how mistakes can arise during the DNA copying process.

Targeting bacterial multidrug resistance - Multidrug resistance is a global burden on human health worldwide. It is often due to low copy number plasmids that harbour genes encoding resistance to multiple antibiotics. Investigating the biochemical mechanisms responsible for the stability and segregation of these insidious genetic elements will reveal novel targets that may be used to devise new therapeutic options.
