Researchers have created a method called optovolution that uses light to guide the evolution of proteins with dynamic behaviors. By engineering yeast cells so their survival depended on proteins ...

When scientists want to create a protein that can potentially treat disease, one approach is to begin with a different protein and evolve it in the lab, selecting over many generations for versions ...

Researchers at Scripps have created T7-ORACLE, a powerful new tool that speeds up evolution, allowing scientists to design and improve proteins thousands of times faster than nature. Using engineered ...

Add Yahoo as a preferred source to see more of our stories on Google. Synthesizing new proteins – the building blocks of biological life – is a scientific field of immense potential, and a newly ...

A new platform combines rational protein design with continuous evolution to discover functional molecules more efficiently. In medicine and biotechnology, the ability to evolve proteins with new or ...

Overview of protein engineering strategies. Directed evolution mimics natural selection in the laboratory through iterative rounds of mutagenesis and screening. Rational design uses structural and ...

Schematic of the T7-ORACLE system. The genome is maintained by the non-mutagenic host replisome (gray), while an orthogonal T7 replisome (red) maintains only a dedicated plasmid (OR) at 100,000-fold ...

Recent research showed that an artificially constructed RNA self-replicating system modeling primitive life at the origin of life evolved to become more prone to extinction under certain experimental ...

Directed Evolution (DE) is a method developed by Nobel laureate Frances Arnold to improve protein fitness for specific applications. However, DE can be less efficient when mutations show epistatic ...

A new LMU study shows how proteins function reliably even without a stable 3D structure—and the crucial importance not only of short sequence motifs, but also of chemical characteristics. Many ...
