ECF transporter, substrate-specific component
Energy-coupling factor (ECF) transporters consist of a substrate-specific component (known as the S component), and an energy-coupling module. The substrate-binding component is a small integral membrane protein which captures specific substrates and forms an active transporter in the presence of the energy-coupling AT module.
