New “evolution engine” creates super-proteins 100,000x faster
"This is like giving evolution a fast-forward button," says co-senior author Pete Schultz, the President and CEO of Scripps Research, where he also holds the L.S. "Sam" Skaggs Presidential Chair. "You can now evolve proteins continuously and precisely inside cells without damaging the cell's genome or requiring labor-intensive steps." Directed evolution is a laboratory process that involves introducing mutations and selecting variants with improved function over multiple cycles. It's used to tailor proteins with desired properties, such as highly selective, high-affinity antibodies, enzymes with new specificities or catalytic properties, or to investigate the emergence of resistance mutations in drug targets. However, traditional methods often require repeated rounds of DNA manipulation and testing with each round taking a week or more. Systems for continuous evolution -- where proteins evolve inside living cells without manual intervention -- a...
