Type IV pili dependent DNA repair in Sulfolobales
, 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.

STRUCTURE-FUNCTION AND BIOGENESIS OF THE TYPE IV PILI
Annual Review of Microbiology, 1993Type IV pili are adhesins expressed by a number of diverse gram-negative microorganisms. These pili are related through similarities in the primary amino acid sequences of the structural subunits, a conserved assembly machinery, and a similar mechanism of transcriptional regulation.

Type IV pili and cell motility
Molecular Microbiology, 1999Type IV pili (Tfp) mediate the movement of bacteria over surfaces without the use of flagella. These movements are known as social gliding in Myxococcus xanthus and twitching in organisms such as Pseudomonas aeruginosa and Neisseria gonorrhoeae. Tfp are localized polarly. Type IV pilins have a signature N‐terminal domain, which forms a coiled‐coil with

Type IV Pili and Twitching Motility
Annual Review of Microbiology, 2002▪ Abstract Twitching motility is a flagella-independent form of bacterial translocation over moist surfaces. It occurs by the extension, tethering, and then retraction of polar type IV pili, which operate in a manner similar to a grappling hook. Twitching motility is equivalent to social gliding motility in Myxococcus xanthus and is important in host

Purification of Type IV Pili and Pilin Subunits
2019The Type IV pili are displayed peritrichously on the surfaces of Neisseria gonorrhoeae cells. Here we present protocols for isolating and purifying Type IV pili and dissociating them into PilE pilin subunits. Pilus filaments are isolated from the bacterial cell surface by mechanical shearing and purified by differential precipitation and centrifugation.

Type II Secretion and Type IV Pili of Francisella
Annals of the New York Academy of Sciences, 2007Abstract: Francisella tularensis genomes encode homologues of type IV pili. Though several F. tularensis genes required for Tfp expression are homologous to genes required for type II secretion (T2S), these gene clusters mainly bear structural signatures that are typical of Tfp. There is preliminary evidence that different F.
