TFP
(Type IV pili) |
 |
Essential for twitching motility and natural competence, and contribute to host cell adherence. ... |

MSHA type IV pili
(Mannose-sensitive haemagglutinin type IV pili) |
|
Homology to the mannose-sensitive hemagglutinin pilus of Vibrio cholerae. MSHA bundle-forming pilus is the major filamentous appendage responsible for tissue adherence and colonisation. Essential for biofilm formation. ... |
|
| Tap type IV pili |
|
Polar. Similar to the P. aeruginosa Pil system. Constitutively expressed. The role of the Tap pilus remains to be elucidated, its biogenesis has strong implications in virulence in other ways. TapD, a prepilin peptidase is not only required for the processing of the prepilins before they are incorporated into the pilus filament but also for the processing of the pseudopilins of the T2SS, that are essential for the secretion of many virulence factors. ... |

Type IVa pili. Plays a role in adherence. ... |
|
| Type IV pili |
|
The genomes of the different F. tularensis subspecies. tularensis (type A), holarctica (type B), and novicida, all encode Tfp clusters including six putative pilin genes. ... |
|
| Type IV pili |
|
Also designated as CAP (competence and adherence-associated pili). Contribute to complement-independent binding, perhaps as the ligand for protozoan lectin. ... |
|
| Type IV pili |
|
One or two different loci are used for the expression of the major pilin encoding gene (pilE), whereas various silent genes (pilS) are spread throughout the chromosome. Recombination between pilS and pilE copies leads to changes in the pilin coding sequence and subsequently to the expression of antigenically different pili. Mutations affecting the length of the homopolymeric G-run located in the region encoding the SP of PilC results in on/off changes in piliation. ... |

| Type IV pili |
|
pilA, B, C, D, E, F, M, N, O, P, Q, T, U, V, W, X, Y1, Y2, Z, and fimT, U, V are involved in the biogenesis and mechanical function of pili, pilG, H, I, K, chpA, B, C, D, E, pilS, R, fimS, rpoN, algR, algU, and vfr are involved in transcriptional regulation and chemosensory pathways that control the expression or activity of the twitching motility of the pili. ... |

ChiRP
(Chitin-regulated pilus) |
|
Also known as PilA pilus. PilA is involved in biofilm formation, adherence to human epithelial cells. ... |
|
MSHA pili
(Mannose-sensitive hemagglutinin pili) |
|
Plays important role in biofilm formation. Crucial for surface selection, irreversible attachment, and ultimately microcolony formation. ... |
