Highlighting an important but unexplored area of evolution, scientists at The Scripps Research Institute have found evidence that, over hundreds of millions of years, an essential protein has evolved chiefly by changing how it moves, rather than by changing its basic molecular structure. The work has implications not only for the understanding of protein evolution, but also for the design of antibiotics and other drugs that target the protein in question.
