DIVERSITY AND EVOLUTION OF TYPE IV PILI SYSTEMS IN ARCHAEA [PDF]
Frontiers in Microbiology, 2016 Many surface structures in archaea including various types of pili and the archaellum (archaeal flagellum) are homologous to bacterial type IV pili systems (T4P).

Identification of surprisingly diverse type IV pili, across a broad range of gram-positive bacteria. [PDF]
PLoS ONE, 2011 In Gram-negative bacteria, type IV pili (TFP) have long been known to play important roles in such diverse biological phenomena as surface adhesion, motility, and DNA transfer, with significant consequences for pathogenicity.

Type IV pili in Francisella – A virulence trait in an intracellular pathogen [PDF]
Frontiers in Cellular and Infection Microbiology, 2011 Francisella tularensis is a highly virulent intracellular human pathogen that is capable of rapid proliferation in the infected host. Mutants affected in intracellular survival and growth are highly attenuated which highlights the importance of the ...

Exploring and exploiting the minor pilins of Type IV pili [PDF]
, 2019 Gram-negative bacteria are naturally resistant to large antibiotics in large part because of their impermeable outer membrane. Type IV pili (T4P) are surface-displayed filamentous polymers of major pilin proteins that have the ability to pull substrates through the outer membrane via retraction.

Type IV pili dependent DNA repair in Sulfolobales [PDF]
, 2013 Het proefschrift van Matgorzata Ajon beschrijft een nieuw UV-induceerbaar DNA-uitwisselingssysteem in Sulfolobus-soorten. Deze organismen zijn hyperthermofiele Crenarchaeota die onder extreem hete en zure omstandigheden leven. Om te overleven is het essentieel dat de integriteit van het genoom onder deze condities behouden blijft.

Rapid cytoskeletal response of epithelial cells to force generation by type IV pili. [PDF]
PLoS ONE, 2011 Many bacterial pathogens interfere with cellular functions including phagocytosis and barrier integrity. The human pathogen Neissieria gonorrhoeae generates grappling hooks for adhesion, spreading, and induction of signal cascades that lead to formation ...

Type IV pili of <i>Enterobacteriaceae</i> species. [PDF]
EcoSal PlusABSTRACT Type IV pili (T4Ps) are surface filaments widely distributed among bacteria and archaea. T4Ps are involved in many cellular functions and contribute to virulence in some species of bacteria. Due to the diversity of T4Ps, different properties have been observed for homologous proteins that make

Type IV Pili in Gram-Positive Bacteria [PDF]
Microbiology and Molecular Biology Reviews, 2013 SUMMARY Type IV pili (T4P) are surface-exposed fibers that mediate many functions in bacteria, including locomotion, adherence to host cells, DNA uptake (competence), and protein secretion and that can act as nanowires carrying electric current.

Type IV Pili: dynamic bacterial nanomachines
FEMS Microbiology Reviews, 2021 ABSTRACT Bacteria and archaea rely on appendages called type IV pili (T4P) to participate in diverse behaviors including surface sensing, biofilm formation, virulence, protein secretion and motility across surfaces. T4P are broadly distributed fibers that dynamically extend and retract, and this dynamic activity is essential for their ...
