The project proposed that we could spray proteins into a mass spectrometer, and under certain conditions they would stay folded, allowing us to visualise small molecules bind to them - a process that is the very basis of drug design. Our study, and particularly the technique, captured my imagination and even led to my first scientific publication.
At the time, this was a rapidly emerging technique with many pioneering scientists driving the development of new instrumentation allowing increasingly ambitious experiments – an exciting time to be involved. Recent developments in this field have now enabled intact membrane proteins to be analysed in the same fashion, which represent some of the most desirable drug targets.
I’m currently working on a project that received £1.25M of funding from the UKRI Future Leaders Fellowship scheme. The Fellowship will develop my career for the best part of a decade, and the funding also pays for the specialist equipment we need for mass spectrometry.
The research itself focuses on investigating megasynthases (very large enzymes, or proteins) in fungi, which are responsible for producing a vast number of biologically active natural products with important applications in modern medicine (e.g. lovastatin and cyclosporin). The precise assembly of these complex compounds relies on highly programmed interactions within the enzymes.
Despite the importance of these interactions, they remain poorly understood as they are so difficult to study. It is the greatest remaining problem in our understanding of fungal megasynthases, and represents a huge obstacle to rewiring these enzymes towards user-designed molecules. We’re applying our state-of-the-art mass spectrometry methods with other complimentary techniques to uncover the molecular factors governing programming.
Once we’ve figured out the ‘molecular rules’, we can try to reprogramme the enzymes to make new versions of these molecules – and potentially help create new or improved drugs. It’s a bit like cracking a code. I’m a big believer in Richard Feynman’s mantra: “what I cannot create, I do not understand” - and perhaps we’ll be creating some new megasynthases soon.
I lead the Jenner Lab here at Warwick, where we’re using our expertise in mass spectrometry and chemical biology to solve complex biological problems. But we’re also part of a wider group of researchers at Warwick who work collaboratively, sharing their expertise and equipment. This interdisciplinary environment is essential to our success and is how modern science is done.
One of the big challenges has been to adjust from doing experiments myself to managing students and post docs, delegating tasks and stepping back from that hands-on role, all in quite a short space of time. I’ve been very fortunate to have some fantastic PhD students in the early years of my lab, who have driven projects forward with their own ideas, which has been fantastic to see.
Going forward, I really want to inspire these students, because I’ve benefited from fantastic mentorship myself. After my PhD at Nottingham with Professor Neil Oldham, I joined Warwick in 2014 as a Postdoctoral Research Fellow under the supervision of Professor Greg Challis, and their support and guidance has undoubtedly helped to shape my career to where it is today.
As I say, I never expected to work in mass spectrometry - but things have turned out rather well.
