The ProVWX complex belongs to the family of ATP-binding cassette (ABC) transporter proteins complexes. It consists of a cytoplasmic ATPase subunit ProV, a transmembrane subunit ProW and a periplasmic binding protein ProX. It is capable of translocating a wide variety of solute (e.g. glycine betaine) across the plasma membrane and is activated under osmotic stress conditions.
