This project aims to use a novel proteomic approach to examine mechanisms of apoptosis at the level of the plasma membrane, mitochondrion, nucleus and cytosol, screening protein extracts of cell organelles by the new technique of SELDI-TOF mass spectrometry in which proteins are adsorbed onto activated chips. This will provide protein mass profiles characteristic of various stages of apoptosis, and will allow identification of proteins of interest by conventional proteomic methods. The establishment of SELDI-MS as a viable tool for cell proteomics would open new opportunities to understand a broad range of cellular functions at the level of protein expression.Read moreRead less

Understanding the molecular mechanism of force generation in the bacterial flagellar motor. The proposed research will advance the knowledge about how the bacterial flagellar motor works, enabling scientists to learn more about nature's blueprint of a nanoscale engine. It will address the fundamental question of how bacterial cells convert electrochemical energy into mechanical energy of rotation.

The proposed research will advance the knowledge about how the bacterial flagellar motor works, enabling scientists to learn more about nature's blueprint of a nanoscale engine. It will address the fundamental question of how bacterial cells convert electrochemical energy into mechanical energy of rotation. At present, the smallest artificial electric motor is still on a micro-, rather than nanoscale. Nanotechnology would therefore benefit from this work by basing their designs on the principles behind the mechanism of the bacterial motor. This research is also of interest for veterinary science, as motility by flagellar motor is a key virulence factor of common animal pathogens associated with, for example, listeriosis and gastroenteritis.Read moreRead less
In situ measurements of the electrostatic properties inside photosynthetic reaction centres: correlation with the energy conversion function of the protein. The photochemical reaction centre is a key protein complex involved in energy conversion. It converts solar energy into chemical energy as a transmembrane charge separation.

The photochemical reaction centre is a key protein complex involved in energy conversion. It converts solar energy into chemical energy as a transmembrane charge separation. Coupling of electron and proton transfer is catalysed at the level of a ubiquinone cofactor. In order to understand how the redox properties of this cofactor are fine tuned by the protein environment, we plan to probe the ubiquinone site using a voltage-sensitive fluorescent dye. This exciting multidisciplinary project will contribute to the understanding of how protein matrices influence and govern the midpoint redox potential of their cofactors and the environments of theirRead moreRead less

This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes. Recent determination of the crystal structure of channel proteins has enabled construction of models that can relate channel function to its structure--necessary for understanding their operation and seeking cures for diseases caused by their malfunction. This project aims to develop accurate ion-protein-water interactions for permeation models based on stochastic and molecular dynamics simulations using both classical and quantum mechanical methods.Read moreRead less
