ABCtransportøren
ABCtransportøren is a term used in Danish biology to denote the ATP-binding cassette (ABC) transporters, a large and evolutionarily conserved family of membrane proteins that use energy from ATP hydrolysis to move substrates across cellular membranes. The core feature, reflected in the name, is the presence of two nucleotide-binding domains (NBDs) that bind and hydrolyze ATP, and typically two transmembrane domains (TMDs) that form the substrate pathway.
ABCtransportøren proteins can function as importers or exporters, depending on the organism and substrate; in bacteria
The mechanism involves ATP binding to the NBDs, triggering conformational changes in the TMDs that translocate
