Do protons really tunnel in enzymes?

It is a great feeling when you finish a paper you have been working on for a long time.

I just finished (I hope!) a paper, Quantum transition state theory for proton transfer reactions in enzymes, that I wrote with my former students, Jacques Bothma and Joel Gilmore.
I plan to put it on the arxiv early next week and then submit it to Journal of Chemical Physics.

Comments welcome!

The recent book cover below shows the timeliness of the topic.
