Artificial Proteins

摘要

Scientists at the University of Pennsylvania have designed and built a protein that can transport oxygen. The protein is much simpler than the oxygen-carrying proteins found in nature, and the process that they used demonstrates a new method for making novel proteins.rnWhy it matters: A more complex version of the protein could eventually be used to create artificial blood. The research also illustrates the effectiveness of the new design process, which could be used to engineer other proteins that improve on the efficiency of important
