Molecular structures can serve to either validate or rule out existing hypotheses, and they can also spawn new, deeper proposals about biochemical mechanism. In this issue of Structure, Schönegge et al. use single-particle cryo-electron microscopy and flexible docking to examine the function of human tripeptidyl peptidase II, including the role of conformational changes in enzyme activation.
