| description | A complex for the transport of metabolites into the cell, consisting of 4 subunits: a transmembrane substrate-binding protein (known as the S component), and an energy-coupling module that comprises two ATP-binding proteins (known as the A and A' components) and a transmembrane protein (known as the T component). Transport of the substrate across the membrane is driven by the hydrolysis of ATP. |
