Predicted 3D structures of the ancestral nitrogenase DDKK complex from oldest to modern. University of Wisconsin-Madison/Holly Rucker NASA-supported scientists have resurrected an enzyme first used by organisms on Earth 3.2-billion years ago and, in the process, have validated a chemical biosignature in rocks that is used to understand ancient life on Earth. The research provides […]
