2. Protein Engineering on Azurin. Expression Mutagenesis and Characterisation of Copper Site Mutants
Abstract : Azurin belongs to a family of small blue copper proteins or cupredoxins which participate in electron transfer processes in plants and bacteria. The type 1 copper site in these proteins is characterised by an intense blue colour, a narrow hyperfine coupling in the EPR signal and, generally, a high reduction potential. READ MORE

3. Advances in Ligand Binding Predictions using Molecular Dynamics Simulations
Abstract : Biochemical processes all involve associations and dissociations of chemical entities. Understanding these is of substantial importance for many modern pharmaceutical applications. In this thesis, longstanding problems with regard to ligand binding are treated with computational methods, applied to proteins of key pharmaceutical importance. READ MORE

4. Asymmetric [2,3]-Sigmatropic Rearrangement of Allylic Ammonium Ylides
Abstract : The thesis describes the realization of an asymmetric [2,3]-sigmatropic rearrangement of achiral allylic amines. It is divided into two parts; the first part deals with the development of a Lewis acid-mediated [2,3]-sigmatropic rearrangement and the second the asymmetric version thereof. READ MORE

5. The Folding Energy Landscape of MerP
Abstract : This thesis is based on studies, described in four papers, in which the folding energy landscape of MerP was investigated by various techniques. MerP is a water-soluble 72 amino acid protein with a secondary structure consisting of four anti-parallel β-strands and two α-helices on one side of the sheet in the order β1α1β2β3α2β4. READ MORE
