Big on Small Things

Prokaryotic Cytokinesis: Little Rings Bring Big Cylindrical Things

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.

Hollow polyhedral structures in small gold-sulfide clusters.

Using ab initio methods, we investigate the structural evolution of a family of gold-sulfide cluster anions (Au(m)S(n)(-)). We show that this family of clusters exhibits simple size-evolution rules and novel hollow polyhedron structures. The highly stable Au(m)S(n)(-) species such as Au(6)S(4)(-), Au(9)S(5)(-), Au(9)S(6)(-), Au(10)S(6)(-), Au(11)S(6)(-), Au(12)S(8)(-), and Au(13)S(8)(-) detecte...

Ulrike Eggert: Big things from small molecules

JCB • VOLUME 194 • NUMBER 3 • 2011 352 Y ou can learn a lot if you have the right tool to help your investigations along. But where those tools don’t exist, you may have to work on a different question. Ulrike Eggert isn’t about to let a little thing like the lack of a tool get in her way—she’ll just make her own. Since her postdoc in Tim Mitchison’s lab at Harvard (1), Eggert has used a combin...
