This domain corresponds to the C-terminal intermembrane space (IMS) region from protein accumulation and replication of chloroplasts 6 (ARC6) and its paralogue PARC6 [1]. ARC6 and PARC6 are components of the plastid division machinery which are essential for the chloroplast replication process [1,2], which implies the assembly and constriction of the tubulin-like FtsZ ring on the stromal surface of the inner envelope membrane (IEM) and the dynamin-like ARC5 ring on the cytosolic surface of the outer envelope membrane (OEM). ARC6 is evolutionarily related to the cyanobacterial cell division protein Ftn2/ZipN [1], having similar structures. This domain from ARC6 and PARC6 interacts with PDV2 and PDV1 respectively. PDV proteins recruit dynamin-like ARC5 ring to the chloroplast surface and mediates its constriction. ARC6/PARC6 are key to connect and coordinate Fst and ARC5 rings during fission [3,4].	Domain
