Synthetic biologists have taken evolution of proteins into their own hands by changing some that occur in nature or even by synthesizing them from scratch. Such engineered proteins are used as highly efficacious drugs, components of synthetic gene circuits that sense biological signals, or in the production of high-value chemicals in ways that are more effective and sustainable than petroleum-based methods.
