Abstract:Molecular dynamics simulations in explicit water were carried out for two stacks, each composed of six 10-strand antiparallel β-sheets for two peptides corresponding to the diverging turn of two homologous Abl-SH3 domains. The first system, referred to as 10×6×MK contained the DLSFMKGE sequence from the Drosophila, while the second one, referred to as 10×6×KK, contained the human DLSFKKGE sequence. It was found that the 10×6×MK β-sheet stack is stable, but the 10×6×KK β-sheet stack is not. The stability of the… 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.
