This document is a copy of one of Marjory Stephenson's, along with her colleague L.H. Strickland, most important papers, the discovery of the hydrogenase enzyme. It is just one of her many research papers on enzymes that laid the foundation for detailed studies of metabolism, both in bacteria and higher-level organisms.
