Technological advances in cryo-EM in recent years have given rise to detailed atomic
structures of bacteriophage tail tubes—a class of filamentous protein assemblies that could …

Bacteria need to deliver large molecules out of the cytosol to the extracellular space or even
across membranes of neighboring cells to influence their environment, prevent predation …

Endosymbiotic bacteria have evolved intricate delivery systems that enable these organisms
to interface with host biology. One example, the extracellular contractile injection systems …

Contractile injection systems (CISs) are phage tail-related structures that are encoded in
many bacterial genomes. These devices encompass the cell-based type VI secretion …

Most bacteriophages present a tail allowing host recognition, cell wall perforation, and viral
DNA channeling from the capsid to the infected bacterium cytoplasm. The majority of tailed …

Ixotrophy is a contact-dependent predatory strategy of filamentous bacteria in aquatic
environments for which the molecular mechanism remains unknown. We show that predator …

Contractile injection systems (CISs) mediate cell–cell interactions by phage tail-like
structures, using two distinct modes of action: extracellular CISs are released into the …

R-type bacteriocins are minimal contractile nanomachines that hold promise as precision
antibiotics,,–. Each bactericidal complex uses a collar to bridge a hollow tube with a …

Sulfate-coupled anaerobic oxidation of methane (AOM) is performed by multicellular
consortia of anaerobic methanotrophic archaea (ANME) in obligate syntrophic partnership …

Contractile injection systems (CIS) are bacteriophage tail-like structures that mediate
bacterial cell–cell interactions. While CIS are highly abundant across diverse bacterial …
