11. Enthalpy and Entropy in Enzyme Catalysis : A Study of Lipase Enantioselectivity
Sammanfattning : Biocatalysis has become a popular technique in organic synthesis due to high activity and selectivity of enzyme catalyzed reactions. Enantioselectivity is a particularly attractive enzyme property, which is utilized for the production of enantiopure substances. LÄS MER
12. Enzyme substrate solvent interactions : a case study on serine hydrolases
Sammanfattning : Reaction rates and selectivities were measured for transacylation of fatty acid esters in solvents catalysed by Candida antarctica lipase B and by cutinase from Humicola insolens. With these enzymes classical water-based enzymology can be expanded to many different solvents allowing large variations in interaction energies between the enzymes, the substrates and the surrounding.

13. Biophysical investigations of ribonucleotide reductase : Activation and inhibition mechanisms
Sammanfattning : Ribonucleotide reductase (RNR) is the enzyme responsible for de novo synthesis of deoxyribonucleotides, needed for both synthesis and repair of cellular DNA. The RNRs known so far are divided into three distinct classes; I, II and III. The conventional class I enzyme is composed of two separate subunits. LÄS MER

15. Novel methods to synthesize aliphatic polyesters of vivid architectures
Sammanfattning : Cross-linked films of ε-caprolactone (CL) and 1,5-dioxepan-2-one (DXO) having various mole fractions of monomers and different cross-link densities were prepared using 2,2’-bis-(-caprolactone-4-yl) propane (BCP) as cross-linking agent and Sn(Oct)2 as catalyst. Reaction parameters were examined to optimize the film-forming conditions. LÄS MER
