This project will attempt to modify biocatalysts so that they can catalyze industrially relevant reactions. The first objective is to identify and extend the essential catalytic elements in epoxide hydrolases in order for them to accept external nucleophiles. Ability of the epoxide hydrolases to accept external nucleophiles could lead to non-natural but synthetically useful reactions. The second objective is to identify and extend the essential catalytic elements in hydroxynitrile lyase in order for them to accept carbon nucleophiles other than cyanide. This objective could also lead to non-natural but synthetically useful reactions.With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Professor Romas J. Kazlauskas of the Department of Biochemistry at University of Minnesota-Twin Cities. Professor Kazlauskas's research efforts revolve around the modification of biocatalysts to catalyze non-natural but synthetically useful reactions. Such reactions are environmentally friendly, as they reduce costs as well as pollution. These reactions could improve the preparation of fine chemicals, which are needed in chemical and pharmaceutical industries.

该项目将尝试修改生物催化剂，使其能够催化工业相关的反应。 第一个目标是确定和扩大环氧化物水解酶的基本催化元素，以使它们接受外部亲核试剂。 环氧化物水解酶接受外部亲核试剂的能力可导致非天然但合成有用的反应。 第二个目标是识别和扩展羟基腈裂解酶中的基本催化元素，以便它们接受氰化物以外的碳亲核试剂。 这一目标也可能导致非天然但合成有用的反应。有了这个奖项，有机和大分子化学计划支持明尼苏达大学双城分校生物化学系的Romas J. Kazlauskas教授的研究。 Kazlauskas教授的研究工作围绕着生物催化剂的改性，以催化非天然但合成有用的反应。 这种反应是环境友好的，因为它们降低了成本和污染。 这些反应可以改善精细化学品的制备，这是化学和制药工业所需要的。
