Free radical mechanism of ferritins
A PhD studentship will be available at the Biomedical EPR Facility to study ferritins – ubiquitous enzymes that accumulate iron for cell’s needs and handle iron’s intrinsic toxicity. Ferritins from different organisms exhibit structural differences and, consequently, demonstrate rather different mechanisms of iron acquisition. We recently demonstrated , that iron acquisition in E. coli ferritin is associated with free radical formation on the enzyme. The mechanism of this free radical driven iron mineralisation, in ferritins from different organisms, is in the focus of the PhD studentship programme. Successful output of the programme is expected to be accurate kinetic characterisation, by several spectroscopic methods, of the mineralisation process which would allow creation of kinetic models. The candidate is expected to be fluent in basic biochemistry, to be familiar with several spectroscopic methods including fast kinetic techniques. Knowledge of and experience in EPR spectroscopy will be considered advantageous. Successful candidate will benefit from learning several wet lab and computational protocols exercised in the friendly and diverse research environment of the School as well as from collaborative contacts with the University of East Anglia which has very a strong record of ferritins studies. The candidates are expected to speak fluent English.
