This knowledge will provide the rational basis for development of in silico methods for predicting digestibility of proteins, a cornerstone of genetically modified organism (GMO) allergenicity risk assessment. We propose to compare the pH-induced unfolding pathways of birch pollen allergen superfamily members (Bet v 1, Mal d 1 and Api g 1), define its impact on patterns and pathways of proteolysis, and investigate the effects of mutations on this process. Unfolding will be characterised using CD, FT-IR and NMR spectroscopy as a function of pH. Unfolding experiments will be also performed in silico using Molecular Dynamics simulations on Cray supercomputer. In silico denatured states will be compared against NMR results, thus describing the contribution of entropic and enthalpic processes to unfolding. The student will receive a broad training in protein structure and characterisation, spanning protein biochemistry, heterologous expression and purification, proteolysis, proteomics, low resolution spectroscopy (fluorescence, CD and FT-IR) together within silico protein structure modelling and IgE-binding studies. This will be complemented by training in protein NMR spectroscopy, covering multidimensional spectral acquisition, processing and assignment, structure calculation, and relaxation analysis. In addition to experimental studies the student will be trained to undertake molecular dynamics techniques for protein unfoldingin silico. Transferable skills training will include presenting to and interacting with Professor Mills Food and Health Network Allergy cluster which includes industry and academic researchers with an interest in allergy. Qualifications: The candidate should be able to demonstrate an aptitude for structural biology. The particular areas include protein biochemistry, protein NMR, and structural biology. Funding: The studentship covers UK/EU tuition fees and an enhanced rate stipend in the region of £16,600 per annum as a result of funding restrictions it is available only to UK/EU students. Overseas student should NOT apply. Successful applicants will be interviewed as part of the studentship competition. Enquiries: Informal enquiries regarding the project should be directed to the project supervisors: Clare Mills E-mail: clare.mills@bbsrc.ac.uk Tharin Blumenschein E-mail: t.blumenschein@uea.ac.uk Web-pages: http://www.ifr.ac.uk/profile/clare-mills.as http://www.uea.ac.uk/che/tb How to apply: For further information and an application form, please visit the 'How to Apply' page on our website: http://www.ifr.ac.uk/students/admissions.htm Contact information: Graduate Studies Office, John Innes Centre, Norwich Research Park, Colney, Norwich, NR4 7UH, UK Telephone: +44(0) 1603 450768 E-mail:graduates.nrp@bbsrc.ac.uk ----------------------------------------- Dr. Tharin Blumenschein, Lecturer t.blumenschein@uea.ac.uk School of Chemistry University of East Anglia Norwich - NR4 7TJ United Kingdom Phone: +44 (0)1603 59 2963https://blogger.googleusercontent.co...s.blogspot.com More... |
