Epistasis arises from shifting the rate-limiting step during enzyme evolution of a β-lactamase
Nature Catalysis - The reasons for epistasis, wherein mutations interact non-additively, are often not fully understood. Now it is found that shifting the rate-limiting step from substrate binding...

Are you interested in how #epistasis shapes the AMR evolution?
We showed that epistasis can be caused by independently modulating substrate binding and the chemical step ultimately changing the rate-limiting step in the catalytic cycle. @NatureCatalysis

Nature goes full open review!
I have complicated feelings about how and when this was achieved!
And they should be apparent to you after even a moment’s thought about the subtext here!

Transparent peer review to be extended to all of Nature’s research papers
From today, all new submissions to Nature that are published will be accompanied by referees’ reports and author responses — to illuminate the process of producing rigorous science.
