In this case, the transport is achieved without a Many transporters of Gram-negative bacteria in- volved in the extracellular secretion of proteins and the periplasmic intermediate. Numerous transporters of Gram- efflux of toxic molecules operate by forming intermem- negative bacteria involved in the extracellular secretion of pro- brane complexes. These complexes are proposed to span tein and the efflux of toxic molecules were shown to operate by both inner and outer membranes and create a bridge forming intermembrane complexes (reviewed in Refs. 2 and 3). across the periplasm.
