How do ABC transporters drive transport?

Abstract Members of the ATP-binding cassette (ABC) superfamily are integral membrane proteins that hydrolyze ATP to drive transport. In the last two decades these proteins have been extensively characterized on a genetic and biochemical level, and in recent years high-resolution crystal structures of several nucleotide-binding domains and full-length transporters have extended our knowledge. Here we discuss the possible mechanisms of transport that have been derived from these crystal structures and the extensive available biochemical data.
