The 2-keto-3-deoxygluconate permease transports the degraded pectin products into the bacterial cell, where they serve as carbon and energy sources. This is a hydrogen coupled transport system (By similarity). Induced by galacturonate and negatively regulated by the KdgR repressor. Is subject to catabolite repression by glucose involving the ccpA gene. Belongs to the KdgT transporter family.
