Professor of Biological Chemistry
Understanding of enzyme-catalysed reactions, using a combination of the following techniques: synthesis of enzymatic substrates and inhibitors, isotope labeling experiments, enzyme purification, and enzyme kinetics. Major areas of interest are enzymes involved in the bacterial degradation of lignin and aromatic compounds, and enzymes involved in bacterial cell wall peptidoglycan biosynthesis, as targets for the development of novel antibacterial agents.

I am working on the following projects at the moment:
- EU Horizon H2020 Project “Zero waste lignocellulosic biorefineries by integrated lignin valorization” (ZELCOR) Co-ordinator S Baumberger (INRA Versailles). EU Horizon 2020 Bio-based Industries Consortium, grant agreement no. 720303.
- BBSRC-FAPESP Project “Lignin valorization in lignocellulosic bioethanol plants: biocatalytic conversion via ferulic acid to high value chemicals” led by Prof Tim Bugg, Dr. Fabio Squina (Univ Sorocaba), BBSRC reference BB/P01738X/1.
My research group is currently studying bacterial enzymes for degradation of the lignin biopolymer found in plant cell walls, including DyP-type peroxidase enzymes, multi-copper oxidase enzymes, and Sphingobacterium sp manganese superoxide dismutase, for the conversion of lignin into renewable aromatic chemicals. We are also using metabolic engineering to convert lignin into high-value aromatic chemicals. My group also studies enzymes involved in bacterial cell wall peptidoglycan biosynthesis, as targets for the development of novel antibacterial agents.
Prof Tim Bugg teaches on the following modules:
CH271 Introduction to Biological and Medicinal Chemistry (10 lectures on enzyme-catalysed reactions, medicinal chemistry)
CH3F9 Molecular Pharmacology (module leader)
CH3F7 Energy (2 lectures on biofuels)
CH3F8 Advanced Co-ordination and Bio-inorganic Chemistry (2 lectures on metallo-oxygenase enzymes)
CH411 Advanced Chemical Biology (module leader, 7 lectures on protein engineering, RNA & peptide libraries, metabolic engineering)
I am supervising the following PhD students:
- Rachel Kerr, Peptidomimetic inhibitors of the protein E-translocase MraY interaction site as new antibacterial agents.
- Timur Avkiran, Inhibitors of Mycobacterium tuberculosis MptpB (co-supervisor).
- Awatif Alruwaili, A bacterial oxidase enzyme involved as an accessory enzyme in lignin degradation.
- Purwinda Iriani, Conversion of brown coal lignite into aromatic chemicals via bioconversion.
Students interested in joining the research group should please contact Professor Tim Bugg.
