The specific mechanisms of enzyme function
WebAs distinct protein sequences encounter different evolutionary bottlenecks, different mechanisms are likely to emerge along evolutionary trajectories toward improved function. Identifying the specific mechanism(s) that need to be improved upon, and tailoring our engineering efforts to each sequence, may considerably improve our chances to ... WebJul 23, 2024 · The presence of a long-lived inactive population of many PafA variants emphasizes how different underlying (and unexpected) biophysical mechanisms can compromise an enzyme’s activity and thus the need to explicitly decouple effects on folding and catalysis to understand function.
