Graphs of dynamic H-bond networks: from model proteins to protein complexes in cell signaling
Autor: Michalis Lazaratos, Konstantina Karathanou, Ana-Nicoleta Bondar
Publikováno v: Current opinion in structural biology. 64
Proton transfer reactions are ubiquitous in biology, as they are involved in the functioning of numerous proteins. Studies of model proteins have revealed mechanisms by which proteins use hydrogen-bond networks for proton transfers, and couple proton
