1. Aldolases for Enzymatic Carboligation : Directed Evolution and Enzyme Structure-Function Relationship Studies
Abstract : The research summarized in this thesis focuses on directed evolution and enzyme mechanism studies of two aldolases: 2-deoxyribose-5-phosphate aldolase (DERA) and fructose-6-phosphate aldolase (FSA).Aldolases are nature’s own catalysts for one of the most fundamental reactions in organic chemistry: the formation of new carbon-carbon bonds.

2. Rational redesign of Candida antarctica lipase B
Abstract : This thesis describes the use of rational redesign to modify the properties of the enzyme Candida antarctica lipase B. Through carefully selected single-point mutations, we were able to introduce substrate-assisted catalysis and to alter the reaction specificity. READ MORE

3. 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

4. Sorting nexin 9 in clathrin-mediated endocytosis
Abstract : Clathrin-mediated endocytosis is a process by which cells can internalise diverse molecules such as nutrients, antigens and signalling-surface receptors. The creation of clathrin-coated vesicles demands interplay between the plasma membrane lipids, cargo molecules and the proteins that build up the coat. READ MORE

5. The transaldolase family : structure, function and evolution
Abstract : The transaldolase gene family includes representatives from all kingdoms of life and the encoded enzymes are important for carbohydrate metabolism. The family can be divided into two subfamilies; Classical transaldolases and the MipB/TalC proteins. READ MORE
