My laboratory uses NMR (and other methods where appropriate) to determine the structure and dynamics of proteins in solution and to study their interactions with ligands. In addition we are developing new methods for characterising structures. Further details are in my web page, linked on the right. Recent work includes:
We have been developing new tools to characterise volume fluctuations in proteins, which occur on timescales between ns and ms. In particular, we have shown that changes in the NMR spectrum resulting from hydrostatic pressures of up to 2 kbar can be used to show how proteins move, and also how they start to denature under pressure. The mobilities are greatest at the active site, and usually involve buried water molecules, which are very important for increasing local flexibility (Figure 1).
We have demonstrated that exposed salt bridges are not energetically favourable in solution, even though they are often observed in crystals.
In collaboration with Prof Hunter in MBB, we have determined structures for two trans-membrane proteins involved in bacterial light-harvesting. The structures are very similar in organic solvents and in micelles. These structures have been used to model the intact photosynthetic complex.
We have studied how proteins recognize polysaccharides such as starch, cellulose and xylan. The activities of enzymes that degrade these plant polymers tend to be organized into ‘cellulosomes’ which are large assemblies of many different enzymes. We have determined the structure of the key assembly component of the anaerobic cellulosome and showed that it probably relies on protein / carbohydrate recognition to assemble. We have also looked at the LysM module which recognises peptidoglycan and chitin, as found in bacterial and fungal cell walls and intertebrate exoskeletons.
We have a longstanding interest in polyphenols such as those from tea, and in how they interact with the body. As part of this study, we have shown that the main component of green tea, epigallocatechin gallate, has the potential to slow down HIV infection.

Mike Williamson's personal page
This page contains a more detailed summary of my research and interests than my main home page.
1975-1978 Natural Sciences, Clare College, Cambridge University (I)
1995 Fellow of the Royal Society of Chemistry and chartered chemist
My research concentrates on protein structure and function, mainly by means of NMR, and is described in more detail below.
I also teach NMR and protein structure, signalling, membranes and molecular motors, as well as numerical and statistical methods. I was a reviewer for the HEFCE QAA Molecular Biosciences reviews in 1998-2000, and coincidentally led the MBB submission, in which we got 24/24. I also headed up the departmental Independent Evaluation of Teaching in 2008, which was also highly complimentary of our teaching. I have been involved in a number of University committees, mostly on admissions, finance and personnel.
I was (2009-2011) Chair of the UK NMR discussion group (for which I now look after the website); also (2009-2012) Chair of the Biochemical Society theme panel II (Molecular structure and function); (2009-2013) a member of BBSRC Committee D (Molecules, Cells and Industrial Biotechnology); and (2005-2009) secretary of Euromar.
I was on sabbatical in Osaka, Japan from September 2008 until September 2009, mainly to write a book, entitled How Proteins Work, published by Garland Press in July 2011 and available online and in all good bookshops. Also available in Italian and Japanese translations.
During my PhD I used NMR to look at the structure and interactions of antibiotics mainly related to vancomycin, still a vital drug in the constant battle against bacterial drug resistance. This led to an interest in the NOE, where I worked first on 1D NOEs, showing that by using a viscous solvent you can make small molecules behave like bigger ones, and determined the definitive structure of vancomycin.
Since then, I have worked both on NMR methodology and on determination of protein structures by NMR. In methodology, I have worked in four main areas:
I have worked on a number of protein systems:
These are protein modules that are used to attach degradative enzymes to their substrate, such as starch, cellulose, xylan and other cell-wall constituents, and also used by bacteria to modify their own or other bacterial cell walls. Our main interest has been in how they recognise specifically their targets, which are chemically very similar: it turns out to be mainly steric rather than using hydrogen bonding. The work has mainly been structural, though we have also worried about enthalpy and entropy, and even a bit of enzymology.
This is a large membrane complex, which traps sunlight and feeds it to the reaction centre. We have used organic solvents and micelles to study some of the component peptides. When combined with other work, in particular electron microscopy and atomic force microscopy, together with a large body of mutagenesis and functional studies, this has allowed us to construct an atomic model of the entire complex.
Salivary proline-rich proteins (PRPs) are the major proteins in parotid saliva. A major function appears to be to bind to plant polyphenols (tannins), which we consume in tea, coffee, wine and many fruits and cereals and are responsible for the sensation of astringency. They are unstructured proteins, so their binding is quite different from the more specific interactions that we are more used to seeing for proteins. The study has involved NMR as well as a wide range of other biophysical techniques.
The RegAB two-component signalling system
This is a classic bacterial two-component signalling system, in which an external stimulus (in this case oxygen tension) leads to phosphorylation of a membrane-bound kinase, which then phosphorylates an intracellular response regulator. The phosphorylated regulator undergoes a conformational change, binds to DNA and alters transcription. We expressed it in functional form, showed how it works, and how the DNA is recognised.
The structure of silk is surprisingly poorly understood. In a longstanding collaboration with Prof Tetsuo Asakura at the Tokyo University of Agriculture and Technology, we have worked on protein chemical shifts and also on methods for characterising silk structure, by solution state and solid state NMR. In the silk worm gland, silk is present in a form called Silk I; the better known fibrous form is called Silk II.We recently showed that the crystalline form of silk consists of two different packing arrangements in close proximity. The silk work led to a 2012 publication in Angewandte Chemie in which we show that antiparallel polyalanine crystallises in two different forms depending on its length. This is interesting first because it suggests that spider dragline silk may derive some of its remarkable strength from its polycrystalline form, and second because the completely linear strands have a rather different position in the Ramachandran plot compared to most beta strands: they are distinctly to the left of standard beta-sheet conformation. This suggests that (a) it takes very little energy to distort a beta-strand conformation, and (b) the phi/psi combination (particularly phi) looks to be strongly related to the twistedness of the strand.
In 2014/15 we published three significant papers. Two of these (Okushita et al (2014) Macromolecules 47:4308-16 and Asakura et al (2015) Macromolecules 48:28-36) show definitively that although silk II is indeed an antiparallel beta sheet, it has two different packings, both different from the classic model proposed by Pauling in 1955. The third (Asakura et al (2015) Macromolecules 48:2345-2357) is a review of what is now understood about the structures of silk I and silk II, particularly as understood from NMR.
We have recently started to be interested in the Hofmeister series. This is a rank ordering of anions, which affect protein stability and solubility. Anions at one end (eg sulphate, phosphate) tend to be highly charged, stabilise proteins but make them less soluble, and are often described as kosmotropes. Ions at the other end (eg thiocyanate) have low charge density, have the opposite effect, and are often called chaotropes. There is disagreement over how they work. We [Bye et al ACS Omega 2016 1:669-679] measured protein chemical shifts in the presence of Hofmeister ions and showed that they all bind, in similar places, though weakly; but that the Hofmeister effects are likely to be due to effects of the ions on water. Work is ongoing.
More recently we have started work on the signalling scaffold protein SH2B1, whhich contains large regions of intrinsically unstructured protein.
We have undertaken a variety of NMR-related projects, mostly with local academics. These include
I have also written a number of reviews, including a recent Perspective on automated protein structure calculation, an update on NOEs in molecular biology, a survey of chemical shift perturbation (Progr NMR Spectrosc, 2013) [an ISI 'Highly Cited' paper], and a review on pressure-induced chemical shifts as probes for conformational fluctuations in proteins.
I am a keen musician (when I have the time!). I play jazz string bass and bass guitar, and have played the cello and bass, as a member of various orchestras, and also in quartets etc. for relaxation, though not recently.
