During cell elongation, RgsS is situated at the growing cell pole and its position is suggested to be stabilized by interaction with AmiC-processed PG. During divisome assembly, RgsS is recruited to mid-cell possibly by one or more divisome components. During cell division, AmiC-processed PG is formed and probably provides binding sites for RgsS. This is assumed to ensure stabilization of RgsS localization at the new cell pole. We propose that RgsS hallmarks the site for assembly of the new elongasome. In the absence of AmiC-processed PG-RgsS binding, anchoring of RgsS at the new cell pole is weakened. Thus, RgsS might accumulate and promote formation of the new elongasome at the old cell pole.
