摘要: Sequence alignments convincingly demonstrate that FtsZ is a prokaryotic homologue of eukaryotic tubulins. appears to be universal in eubacteria and archaebacteria has also been identified chloroplasts. Like tubulin, it have cytoskeletal role as both proteins assemble into two types characteristic polymers vitro — protofilament sheets mini-rings. Recent advances immunofluorescence the use green fluorescent protein provided clear images localized ring at septation site bacteria, new insights assembly this Z-ring.
