Biography

Bill Broadhurst’s enthusiasm for science was ignited at the age of seven when his father showed him what happens when a lump of metallic sodium is dropped into a bucket of water. The resulting explosion had unexpected consequences, one being his arrival as an undergraduate at University College, Oxford to study Chemistry in 1982. His interests gradually become less incendiary, leading to a DPhil on the effects of magnetic fields on free radical reactions, followed by postdoctoral work in both Oxford and Cambridge into biological applications of nuclear magnetic resonance (NMR) spectroscopy. Since he arrived as an Assistant Director of Research in the Department of Biochemistry in 1995, he has used NMR to investigate the structure, dynamics and interactions of proteins. He joined Emmanuel College as an Official Fellow in 2005 and became a University Lecturer in 2015.

Outside the world of work, for the last five years in Cambridge he has been involved in the life of St James' Church,Wulfstan Way

Research

(A) Structural dynamics of modular polyketide synthases

Modular polyketide synthases (PKSs) are among the largest integrated enzyme complexes known, organizing clusters of catalytic domains into assembly lines which produce bioactive products that range from antibiotics to toxins. I am interested in how these systems use global conformational changes, protein-protein interfaces and protein-substrate recognition to control the production of polyketide natural product chains.

(B) Protein-nucleic acid interactions

I am also interested in how NMR spectroscopy can be used to investigate the structural and dynamic properties of protein-DNA and protein-RNA complexes.
