3. 2. Quantum Chemical Modeling of Asymmetric Enzymatic Reactions

   Författare :Maria E. S. Lind; Fahmi Professor; Rajeev Prabhakar; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biocatalysis; enantioselectivity; density functional theory; B3LYP; enzyme; hydrolysis; decarboxylation; Organic Chemistry; organisk kemi;

   Sammanfattning : Computational methods are very useful tools in the study of enzymatic reactions, as they can provide a detailed understanding of reaction mechanisms and the sources of various selectivities. In this thesis, density functional theory has been employed to examine four different enzymes of potential importance for biocatalytic applications. LÄS MER
