Analysis of the heterogenous structural states of the hexameric ATPase PilU of the type IV pili from Vibrio cholerae

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Type IV pili (T4P) mediate surface motility, host interactions, and DNA uptake through cycles of extension and retraction. While the primary retraction ATPase PilT has been extensively characterized, its homolog PilU remains less well understood despite being demonstrated as a PilT‐dependent retraction ATPase.

Neisseria meningitidis-Induced Caspase-1 Activation in Human Innate Immune Cells Is LOS-Dependent

Journal of Immunology Research, 2019
Meningococcal disease such as sepsis and meningitidis is hallmarked by an excessive inflammatory response. The causative agent, Neisseria meningitidis, expresses the endotoxin lipooligosaccharide (LOS) that is responsible for activation of immune cells ...

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, Volume 600, Issue 10, Page 1444-1474, May 2026.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.
