Abstract:

A major area of interest is the identification of proteins that play a role in hormone dependent cancers and in collaboration with the MRC Centre for Reproductive Health we studied the gonadotropin releasing hormone receptor (GnRH-R). Other targets described in the thesis are the SH3 domain of PSD-95 and the protein BLyS. In order to identify potential inhibitory small molecules we have used a variety of computational data base mining approaches as well as using and developing experimental binding assays. It has become increasingly challenging to evaluate the most representative drug like smal

Abstract:

The interactions between proteins and peptides in aqueous solution have been investigated using a classical molecular dynamics procedure with a molecular mechanical representation of the potential energy surface. During post-processing of the trajectory an implicit solvation method has been applied in order to calculate the free energy of each of the complex, protein and peptide structures in solution, allowing the binding free energy of the protein-peptide complex to be evaluated. Entropic contributions have been estimated using classical ideal gas thermodynamics. A program has also been deve

Abstract:

Peptides derived from DNA-binding zinc finger proteins were synthesised with pairs of cysteine residues with i,i+7 and i,i+11 relative spacings introduced into their sequence. The sidechains of these cysteine residues were then alkylated with the well-known water soluble photochrome 3,3’-bis(sulfo)-4,4’-bis(chloroacetamino) azobenzene (BSBCA). The change of shape of the azobenzene dye in these peptide-dye conjugates allowed photocontrol of peptide structure and thus peptide-DNA interactions. For a single zinc finger helix, UV irradiation yielded a peptide conjugate with a dissociation constant

Pathogenic amyloids appear as nanometer sized "plaques" that self-assemble over time. The plaques usually are well-organized crystalline/fibrous struc

MDM2 and MDMX are therefore attractive therapeutic targets due to their role in tumour progression.

Recent approaches to constraining peptide sequences into more structurally-defined α- helical secondary structures, so-called peptide stapling, are discussed. Stapled peptides are a class of therapeutics that have been shown to more effectively target protein-protein interactions, which are harder to target using a classical small-molecule therapeutic approach. Stapling a peptide constrains it into a well-defined secondary structure. This more accurately mimics the protein-protein interaction making the peptide a more viable therapeutic.

Nitrogen is one of the most abundant elements on Earth and mostly found in the atmosphere as the inert gas N2. Therefore the nitrogen cycle is important for maintaining the bioavailabilty of nitrogen for organisms. Denitrification is a process that closes the nitrogen cycle by subsequent conversion of nitrate to dinitrogen with reduction of nitrate to nitrite being the very first necessary step. The bacterial periplasmic nitrate reductase NapA is one of those nitrate reducing enzymes and contains a molybdenum cofactor and a [4Fe-4S] cluster as cofactors.
