Dhruva K. Chakravorty, Bing Wang, Melek N. Ucisik, and Kenneth M. Merz, Jr. , Insight into the Cation−π Interaction at the Metal Binding Site of the Copper Metallochaperone CusF
J. Am. Chem. Soc., 2011-10-26
Abstract: The periplasmic Cu+/Ag+ chaperone CusF features a novel cation−π interaction between a Cu+/Ag+ ion and Trp44 at the metal binding site. The nature and strength of the Cu+/Ag+–Trp44 interactions were investigated using computational methodologies. Quantum-…
