BUTYRYLCHOLINESTERASE POLYPEPTIDE VARIANTS WITH INCREASED CATALYTIC EFFICIENCY AND METHODS OF USE

摘要

The invention provides twenty-five butyrylcholinesterase variants having increased cocaine hydrolysis activity as well as the corresponding encoding nucleic acids. The invention also provides libraries of butyrylcholinesterase variants as well as libraries of the corresponding nucleic acids encoding butyrylcholinesterase variants. The invention further provides methods of hydrolyzing a cocaine-based butyrylcholinesterase substrate as well as methods of treating a cocaine-induced condition.
