Enzyme engineering: New method selectively destroys disease-causing proteins

Scientists have long struggled to target proteins that lack defined structure and are involved in cancer, neurodegenerative disorders like Parkinson's disease, and other serious illnesses. Now, a new study from Scripps Research demonstrates a proof of concept for a new strategy: engineering proteases—enzymes that cut proteins at specific sites—to selectively degrade these elusive targets with high precision in the proteome of human cells.
