摘要

Life falls into three fundamental domains - Archaea, Bacteria, and Eucarya (formerly archaebacteria, eubacteria, and eukaryotes, respectively). Though Archaea lack nuclei and share many morphological features with Bacteria, molecular analyses, principally of the transcription and translation machineries, have suggested that Archaea are more related to Eucarya than to Bacteria. Currently, little is known about the archaeal cell division apparatus. In Bacteria, a crucial component of the cell division machinery is FtsZ, a GTPase that localizes to a ring at the site of septation.
