WebThey share a common architecture consisting of two transmembrane domains (TMDs) and intracellular nucleotide-binding domains (NBDs). In bacterial ABC importers, an additional domain, a solute (or substrate)-binding protein (SBP), serves as an initial receptor that specifically binds to ligands with high affinity, delivers them to TMDs, and stimulates the … WebHowever, rather than moving both transmembrane domains around the substrate, only one domain shifts around the binding site and change the side the substrate is exposed to []. … WebNX_P82251 - SLC7A9 - b(0,+)-type amino acid transporter 1 - Sequence.
