Bacterial ATP-driven transport systems for maltose/maltodextrins (ABC transporter)


members of the protein family of ABC (ATP-binding cassette) transporters, which have been found in all living organisms, some with medical relevance, mediate the uptake or export of solutes across biological membranes at the expense of ATP. Using the binding protein-dependent uptake systems for maltose/maltodextrins of Samonella typhimurium and Alicyclobacillus acidocaldarius as models, we study basic principles of their functions and some aspects of carbon regulation. We study
