Role of type IV pili in predation by Bdellovibrio bacteriovorus. [PDF]
PLoS ONE, 2014 Bdellovibrio bacteriovorus, as an obligate predator of Gram-negative bacteria, requires contact with the surface of a prey cell in order to initiate the life cycle.

Archaeal type IV pili and their involvement in biofilm formation [PDF]
Frontiers in Microbiology, 2015 Type IV pili are ancient proteinaceous structures present on the cell surface of species in nearly all bacterial and archaeal phyla. These filaments are involved in a diverse array of critical cellular processes.

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).

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 ...

Analysis of the heterogenous structural states of the hexameric ATPase PilU of the type IV pili from Vibrio cholerae. [PDF]
Protein SciAbstract 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.

Type IV pili of Enterobacteriaceae 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: 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 ...
