Amino-acid mutations to extend the biological half-life of a therapeutically valuable mutant of human butyrylcholinesterase.

Abstract excerpt

Cocaine is a widely abused and addictive drug without an FDA-approved medication. Our recently designed and discovered cocaine hydrolase, particularly E12-7 engineered from human butyrylcholinesterase (BChE), has the promise of becoming a valuable cocaine abuse treatment. An ideal anti-cocaine therapeutic enzyme should have not only a high catalytic efficiency against cocaine, but also a sufficiently long...
