Organophosphate pesticide degradation: evolved enzymes and biomimetics for bioremediation and medicine. Organophosphate (OP) pesticides are an indispensable part of modern agriculture - their use results in dramatically increased crop yields. However, they are toxic and can damage the environment and cause significant health problems. Enzymes are currently being used to treat runoff water that is contaminated with OPs. The same enzymes also have the potential to aid in the treatment of OP poison ....Organophosphate pesticide degradation: evolved enzymes and biomimetics for bioremediation and medicine. Organophosphate (OP) pesticides are an indispensable part of modern agriculture - their use results in dramatically increased crop yields. However, they are toxic and can damage the environment and cause significant health problems. Enzymes are currently being used to treat runoff water that is contaminated with OPs. The same enzymes also have the potential to aid in the treatment of OP poisoning. However, OP degrading enzymes could be improved in many ways - we will evolve these enzymes to enhance their catalytic properties - to enable them to act more efficiently on an increased number of OPs.

Directed evolution used to probe protein structure and function; new enzymes for bio-remediation and industry. The aim of the research is to generate new and useful enzymes for bio-remediation and other practical applications. For example, we are evolving enzymes to better degrade organophosphate pesticides that are environmental pollutants. Apart from producing useful enzymes, the proposed research aims at gaining a better understanding of how enzymes work and how they evolve. We intend to dete ....Directed evolution used to probe protein structure and function; new enzymes for bio-remediation and industry. The aim of the research is to generate new and useful enzymes for bio-remediation and other practical applications. For example, we are evolving enzymes to better degrade organophosphate pesticides that are environmental pollutants. Apart from producing useful enzymes, the proposed research aims at gaining a better understanding of how enzymes work and how they evolve. We intend to determine the structure of many related enzymes that have been evolved to have enhanced activities. This data will be used to analyze the intricate relationship between sequence, structure and enzyme activity.Read moreRead less
