Abstract:Water plays important but poorly understood roles in the functions of most biomolecules. We are interested in understanding how proteins use diverse search mechanisms to locate specific sites on DNA; here we present a study of the role of closely associated waters in diverse translocation mechanisms. The bacterial DNA adenine methyltransferase, Dam, moves across large segments of DNA using an intersegmental hopping mechanism, relying in part on movement through bulk water. In contrast, other proteins, such as … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
