The structure of the PapD-PapGII pilin complex reveals an open and flexible P5 pocket [PDF]
, 2012 P pili are hairlike polymeric structures that mediate binding of uropathogenic Escherichia coli to the surface of the kidney via the PapG adhesin at their tips.

ssRNA phage penetration triggers detachment of the F-pilus
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Many pathogenic bacteria utilize dynamic appendages called pili to facilitate important functions, such as gene transfer and motility.

Characteristics of E. coli K12 strains carrying both an F prime and an R factor [PDF]
, 1970 The interrelationship between an F prime and an F-like or I-like R factor was studied in Escherichia coli K 12 strains carrying both. The donorability of such strains suggested that these plasmids were transferred independently by their own transfer ...

Variation of pneumococcal Pilus-1 expression results in vaccine escape during Experimental Otitis Media [EOM]. [PDF]
PLoS ONE, 2014 The pneumococcal Pilus-1 enhances attachment to epithelial cells in the respiratory tract and subsequent invasion. Pilus-1 expression is bi-stable and positively regulated by the RlrA transcriptional regulator.

Crystal Structure of the P Pilus Rod Subunit PapA [PDF]
, 2007 P pili are important adhesive fibres involved in kidney infection by uropathogenic Escherichia coli strains. P pili are assembled by the conserved chaperone-usher pathway, which involves the PapD chaperone and the PapC usher.

The Streptococcus pneumoniae pilus-1 displays a biphasic expression pattern. [PDF]
PLoS ONE, 2011 The Streptococcus pneumoniae pilus-1 is encoded by pilus islet 1 (PI-1), which has three clonal variants (clade I, II and III) and is present in about 30% of clinical pneumococcal isolates.

Structural bases for F plasmid conjugation and F pilus biogenesis in Escherichia coli
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Bacterial “sex,” or conjugation, is a central mechanism underlying the proliferation of antibiotic resistance. Despite the discovery of conjugation by F plasmids in Escherichia coli over seven decades ago, we have only now visualized the F ...

Immune exclusion by naturally-acquired secretory IgA to the pneumococcal pilus-1.
Journal of Clinical Investigation, 2020 Successful infection by mucosal pathogens requires overcoming the mucus barrier. To better understand this key step, we performed a survey of the interactions between human respiratory mucus and the human pathogen S. pneumoniae. Pneumococcal adherence to
