The divisome is a protein complex in bacteria that is responsible for cell division, constriction of inner and outer membranes during division, and peptidoglycan (PG) synthesis at the division site. The divisome is nearly ubiquitous in bacteria although its composition may vary between species.[2]
The elongasome is a modified version of the divisome, without the membrane-constricting FtsZ-ring and its associated machinery on the inside of the cell membrane. The elongasome is present only in non-spherical bacteria and directs lateral insertion of PG along the long axis of the cell, thus allowing cylindrical growth.[2]
