title: Prokaryotic cytokinesis: little rings bring big cylindrical things.
abstract: At the division site, most bacteria assemble filaments of the tubulin homolog FtsZ that recruit other proteins into a functional divisome. A recent study describes the in vitro assembly of the divisome component SepF into small rings that organize FtsZ filaments into microtubule-like structures, possibly facilitating efficient septal growth and cytokinesis.
