UNESCO/ L'Oreal Rising Talent Award won by graduate student alumna
Areej Abuhammad Areej Abuhammad, who started her career as a graduate student (2009-2013) working jointly in the Biochemistry and Pharmacology Departments, has won a 2018 UNESCO/L'Oreal Rising Talent Award Published: 19 March 2018
Antisense transcription influences sense transcription
Antisense transcription affects the rate of transcription initiation and nuclear processing of RNA through histone acetylation levels New research by the Mellor and Angel groups, published in Molecular Systems Biology, provides new insights into the biological function of antisense transcription. The results highlight a role of antisense transcription in influencing the production of sense transcripts, ultimately determining the levels of functional protein Published: 19 March 2018
Mechanism of cationic amino acid transport revealed in new crystal structure
Structure of GkApcT with the predicted gating helices shown. Movement of TM6 away from TM3 and 8 opens the binding site to the interior of the cell, and facilitates release of the bound amino acid New research by the Newstead group, published in Nature Communications, reveals the first crystal structure for a bacterial homologue of the mammalian cationic amino acid transporters GkApcT providing insight into amino acid selectivity and transport mechanism in this physiologically important transporter family Published: 27 February 2018
A new class of ion pump inhibitors could help fight infectious fungi

Welcome

Mark Sansom, Head of Department

The Department of Biochemistry at the University of Oxford is a centre for world class research and teaching of all aspects of Biochemistry by staff from many different backgrounds and nationalities. Our research addresses a wide range of questions relating to the fundamental basis of all cellular life from man to microbes. This work explains the structures and functions of proteins and nucleic acids, and in doing so addresses the mechanisms of many human diseases. Using this knowledge, other researchers aim to create new vaccines, antiviral and antibacterial therapies to protect and treat humans across the world.

You can read more about the details of our current work and other aspects of the department, including undergraduate teaching and public outreach activities, on these web pages.

The Biggin group, in collaboration with colleagues from the University of Southampton and industry, has just published a large-scale prediction of water-stability in a family of proteins that are key targets for the treatment of many different cancers. Being able to design compounds that displace these key waters is a common strategy in medicinal chemistry, but knowing which waters to target or if they are even likely to be displaceable at all is an extremely challenging problem. The group employ a method, recently developed by the Essex group in Southampton, called Grand Canonical Monte Carlo (GCMC) to make predictions about which water molecules in bromodomains are likely to be displaceable.

Bromodomains are small protein modules that recognise acetylated lysine on histones and thereby regulate gene expression by recruiting various transcription factors. To date, 61 bromodomains have been found in 46 different human proteins. As such, they are being investigated as a promising epigenetic target for diseases like cancer and inflammation. A few bromodomain inhibitors are in fact already in clinical trials for the treatment of leukaemia, midline carcinoma, and progressive lymphoma. Because of this, there is great interest in further exploring the therapeutic potential of this protein family.

Although there is considerable sequence diversity, bromodomains share very similar binding pockets, which makes the discovery of selective probes challenging. Bromodomains are amenable to study by X-ray crystallography and structures are available for many different types of bromodomain (see Figure 1). The structures revealed a conserved water network formed by four water molecules at the base of the binding site (Figure 1) and it is these waters which, if displaceable, may offer opportunities to gain affinity and/or improve selectivity.
