1. Crystallographic studies of transaldolase : implications for the enzymatic mechanism and the evolution of class I aldolases
Abstract : Transaldolase catalyzes the reversible transfer of a dihydroxyacetone moiety from a ketose donor to an aldose acceptor by forming a Schiff-base intermediate between a Iysine residue and dihydroxyacetone. It belongs to the class I aldolase family. READ MORE

2. Energy Transduction and Sensory Signalling in Haloarchaea Structural Characterisation of the Photocycles of Bacteriorhodopsin and Sensory Rhodopsin II
Abstract : Archaeal rhodopsins belong a subfamily of heptahelical transmembrane proteins. All contain a buried retinal chromophore covalently bound to a conserved lysine residue in helix G via a protonated Schiff base. READ MORE

3. Enantioenriched Cyanohydrins and Acetoxyphosphonates – Synthesis and Applications
Abstract : In this thesis, the synthesis of enantioenriched compounds using novel methodologies that employ metal- and biocatalysis is described.In the first part, the synthesis of enantioenriched cyanohydrins, which are highly versatile synthetic intermediates, is described. READ MORE

4. Energetic processing of complex molecules in the gas phase
Abstract : Collisions between molecules and gas phase targets often lead to various intriguing processes. Such collisions may induce fragmentation of molecules that can be divided into different subsets depending on the projectile, target, and collision energy. READ MORE

5. New Tools for Green Catalysis : Studies on a Biomimetic Hybrid Catalyst and a Novel Nanopalladium Catalyst
Abstract : The first part of this thesis describes an improved synthetic route to hybrid (hydroquinone-Schiff base)cobalt catalysts. Preparation of the 5-(2,5-hydroxyphenyl)salicylaldehyde building block was improved by altering the protective groups of the hydroquinone (HQ) starting material. READ MORE
