I recently finished a lovely collaboration with Greg Finnigan, Tom Stevens, and Joe Thornton. Our work shows how a molecular machine — in this case, a proton pump — increased in structural complexity over evolutionary time. On a personal note, our project demonstrates the type of interdisciplinary work that can emerge when computational skills are combined with “wet” bench work.
Also, W. Ford Doolittle wrote a companion essay about our paper.
