Examples of positive regulation of cell division. (A) During sporulation in S. coelicolor, SsgB interacts with SsgA (complex depicted in dark blue) to mark potential division sites and recruit FtsZ (purple). (B) Cells of M. xanthus uses PomZ (blue) to indicate the site for FtsZ localization and assembly. (C) In S. pneumoniae, MapZ (LocZ; depicted in blue) localizes to the mid-cell division site facilitate the process of FtsZ ring assembly. Just prior to septum formation, a subpopulation of MapZ (light blue) binds to the nascent peptidoglycan during the lateral cell wall synthesis (shown as red line) and hitchhikes to mark the future division sites.
