The FtsX extracellular domain binds the PG peptidase Rv2190c/RipC N-terminal segment, causing a conformational change that activates the enzyme ileading to PG hydrolysis in Mycobacterium tuberculosis. Structural analysis of FtsX ECD reveals fold containing two lobes connected by a flexible hinge. Mutations in the hydrophobic cleft between the lobes showed reduction in RipC binding in vitro and inhibition of FtsX function in Mycobacterium smegmatis [1].

This region contains three transmembrane helices.

ABC transporters are the largest family of proteins in many completely sequenced bacteria. ABC transporters are composed of two copies of this domain and two copies of a transmembrane domain Pfam:PF00664. These four domains may belong to a single polypeptide as in Swiss:P13569, or belong in different polypeptide chains.
