Enhanced biocatalysis in organic solvents for pharmaceutical biotransformation. Enzymes such as hydrolases play an important role in biotechnology because of their extreme versatility with respect to substrate specificity and stereoselectivity. The use of lipases as catalysts for optical isomer-specific organic reactions is often limited by unacceptably low enantioselectivities. We will investigate recombinant enzymes cloned from thermophilic lipolytic bacteria for synthetic reactions in orga ....Enhanced biocatalysis in organic solvents for pharmaceutical biotransformation. Enzymes such as hydrolases play an important role in biotechnology because of their extreme versatility with respect to substrate specificity and stereoselectivity. The use of lipases as catalysts for optical isomer-specific organic reactions is often limited by unacceptably low enantioselectivities. We will investigate recombinant enzymes cloned from thermophilic lipolytic bacteria for synthetic reactions in organic solvents, especially chiral resolution of mixtures in the production of pharmaceutical intermediates. Genetic improvement of lipase enantiospecificity and regioselectivity will be achieved using in vitro evolution by recombination and screening. The outcome will be cost-effective production superior biocatalysts with specifically enhanced regiospecific, enantioselective and hydrolytic characteristics.

Metalloproteins and metalloenzymes. Most of the chemical reactions and physical movements in living systems are carried out by proteins. The information for producing proteins from amino acids is stored in the genes, but many biological processes depend on additional atoms or molecules ('cofactors') that are added to a protein after it is assembled. For example, more than 30% of all proteins contain metal atoms which are essential for their function. We are studying the structures of such meta ....Metalloproteins and metalloenzymes.

We are studying the structures of such metalloproteins and metalloenzymes so that we can better understand their activities with long term aims of creating new molecules for biotechnology and/or drugs.Read moreRead less

Hydrogen-abstraction reactions are of vital importance in the chemical, biochemical and polymerization processes that occur in everyday life. The objective of the proposed research is to improve our understanding of such reactions. State-of-the-art quantum chemistry calculations will be used to examine a broad range of hydrogen-abstraction reactions, and to obtain accurate information about the factors that influence such reactions. Building on this work, more detailed case studies will be performed in two important areas: the hydrogen-abstraction steps in biochemical reactions mediated by coenzyme B12, and chain-transfer processes in conventional and controlled free-radical polymerization.Read moreRead less
