On the cover: Type IV pili (T4P), long and flexible appendages at the surface of many bacteria, are critical virulence factors. Pili of enterohemorrhagic E. coli (EHEC), an important human pathogen, are polymers of the major subunit PpdD. In the quest for drug and vaccine discovery against such pathogens, unraveling the detailed organization and dynamics of PpdD pili will be instrumental. By combining NMR and cryo-EM, Bardiaux et al. (pp. 1082–1093) add a new page to the coloring book of T4P atomic models. The EHEC T4P structure revealed a large extended region of the pilin stem correlating with extremely high pilus flexibility, along with residues crucial for its assembly and stability.

Protein secretion in bacteria is highly specific. Substrates secreted via the Type II secretion nanomachines are fully folded prior to secretion and are specifically recognized in their native state. In some cases, they even […]

Bacterial Transmembrane Signaling
Bacteria display several mechanisms to adapt to their host-environment and successfully colonise it. One important mechanism of adaptation concerns the regulation of gene expression in response to external signals such as the presence of […]
ARIA (Ambiguous Restraints for Iterative Assignment)
Our computer program ARIA (Ambiguous Restraints for Iterative Assignment) is a software for automated NOE assignment and NMR structure calculation. It speeds up and automatizes the assignment process through the use of an iterative […]
