The Structure, Function and Roles of the Archaeal ESCRT Apparatus.

Although morphologically resembling bacteria, archaea constitute a distinct domain of life with a closer affiliation to eukaryotes than to bacteria. This similarity is seen in the machineries for a number of essential cellular processes, including DNA replication and gene transcription. Perhaps surprisingly, given their prokaryotic morphology, some archaea also possess a core cell division apparatus that is related to that involved in the final stages of membrane abscission in vertebrate cells, the ESCRT machinery.
