Assembly and priming of the VPS4B AAA+ ATPase of the human ESCRT system

The cryo-electron microscopy structure of the full-length human VPS4B hexamer in six-membered helical “spiral staircase” states suggests a mechanism for substrate-dependent hexamerization and priming of VPS4 for its ESCRT-III remodeling activity.

Discovery of a buried charge-network GFP-fold family spanning prokaryotes and eukaryotes

Findings expand the known sequence and chemical space of the GFP barrel, although the biochemical function of the network remains unknown, and identify the same two-cation/two-anion/tyrosine network in 238 members of DUF2490, an unrelated outer-membrane beta-barrel family consistent with convergent evolution of the bur...

Detection of Ring Structure and Its Flexibility in Periplasmic Region of FliL, Bacterial Flagellar Stator-Associate Protein, in Marine Vibrio.

Analysis of oligomeric organization and structural plasticity of the periplasmic domain of polar-flagellum FliL from Vibrio alginolyticus and compared with detergent-solubilized full-length pofFliL suggests that such plasticity enables FliL to act as an adaptable scaffold for stator engagement and mechanosensitive remo...

Bacterial Geosmin Biosynthesis is Compartmentalized Inside a Two-Component Protein Shell

It is shown that GeoA cargo loading is mediated by repeating, short cargo loading peptides (CLPs), and that GeoA encapsulation provides benefits for enzyme activity and stability, and provides insights into a putative mode of cargo protein regulation via pore state modulation.
