1. Complement receptor-mediated signal transduction in human neutrophils : A role for protein kinase C in the phagocytic process
Abstract : The neutrophil granulocyte comprises the first line of human defense against invading microorganisms. A versatile motile machinery enables the cell to migrate to the inflammatory site and there engulf and destroy the pathogens by phagocytosis. READ MORE

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. Lipase chemoselectivity - kinetics and applications
Abstract : A chemoselective catalyst is preferred in a chemical reaction where protecting groups otherwise are needed. The two lipases Candida antarctica lipase B and Rhizomucor miehei lipase showed large chemoselectivity ratios, defined as (kcat/KM)OH / (kcat/KM)SH, in a transacylation reaction with ethyl octanoate as acyl donor and hexanol or hexanethiol as acyl acceptor (paper I).

4. Lipase-Catalyzed Syntheses of Telechelic Polyesters
Abstract : Telechelic polyesters have successfully been synthesized with lipase-catalyzed polymerization. The produced telechelics had a high degree of difunctionalization, high purity (requiring little or no workup) and controlled degree of polymerization. The syntheses were performed in one-pot one-step reaction systems. READ MORE

5. Lipase and ω-Transaminase : Biocatalytic Investigations
Abstract : In a lipase investigation, Candida antarctica lipase B (CALB) are explored for enzyme catalytic promiscuity. Enzyme catalytic promiscuity is shown by enzymes catalyzing alternative catalytic transformations proceeding via different transition state structures than normal. READ MORE
