  2. 1. Quantum Chemical Modeling of Asymmetric Enzymatic Reactions

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

    Abstract : 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. READ MORE

  4. 2. Quantum Chemical Modeling of Asymmetric Enzymatic Reactions : Applications to Limonene Epoxide Hydrolase and Arylmalonate Decarboxylase

    Author : Maria E.S. Lind; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis, density functional theory has been employed to study the reactionmechanisms of two enzymes with possible applications in asymmetric biocatalysis.To reproduce and rationalize the stereoselectivity of the enzymes, quite large cluster models that account for the chiral environment of the active site have been used.

    Abstract : Parkinson’s disease (PD) is one of the most common neurodegenerative disorders and it is caused by a loss of dopamine (DA) producing neurons in the basal ganglia in the brain. The PD patient suffers from motor symptoms such as tremor, bradykinesia and rigidity and treatment with levodopa (LD), the precursor of DA, has positive effects on these symptoms. READ MORE
