Photodamaged mitochondria undergo selective mitophagy ( 20 ), which is also consistent with the model that fission provides a form of quality control by segregating damaged parts of mitochondria and targeting them … The FtsZ protein (a homologue to eukaryotic tubulin), found in many bacteria and some archaea, plays a role in mitochondrial fission. The Min system plays a role in localizing and assembling FtsZ proteins into a ring around the center of the mitochondria and some proteins tethered to the inner mitochondrial membrane also help anchor the Z ring. The Z ring is anchored at the site of constriction where division will take place. The Z ring acts as a scaffold for the deposition of sep…
