  • Title: The ATP switch model for ABC transporters.
    Author: Higgins CF, Linton KJ.
    Journal: Nat Struct Mol Biol; 2004 Oct; 11(10):918-26. PubMed ID: 15452563.
    Abstract:
    ABC transporters mediate active translocation of a diverse range of molecules across all cell membranes. They comprise two nucleotide-binding domains (NBDs) and two transmembrane domains (TMDs). Recent biochemical, structural and genetic studies have led to the ATP-switch model in which ATP binding and ATP hydrolysis, respectively, induce formation and dissociation of an NBD dimer. This provides an exquisitely regulated switch that induces conformational changes in the TMDs to mediate membrane transport.
