Regulation of HSAF production by PilR was found to be independent of pilus formation.
3
The CPS and pilus typing results were generally consistent with MLST and BAPS clustering.
4
We discuss the implications of these findings in the context of Type IV pilus retraction regulation.
5
A pulse-chase analysis revealed that a chaperone-PapA complex is a true periplasmic intermediate in pilus assembly.
6
Circulating immunoglobulin G antibody activity to the bundle-forming pilus subunit A was readily detected in all children.
7
The type 1 pilus genes are also thought to be negatively regulated by a large number of repressors.
8
This structural similarity suggests similar functions in usher-mediated pilus biogenesis, playing out at different stages of the process.
9
Little is known about directed motility of bacteria that move by type IV pilus-mediated (twitching) motility.
10
Immunoglobulin A antibody activity to the bundle-forming pilus subunit A was detected in 75% of colostrum samples.
11
However, the mechanism by which type 1 pilus-mediated bacterial invasion contributes to the pathogenesis of a urinary tract infection is unknown.
12
We investigated if differences in type 1 pilus expression may explain TOP52's early defect in vivo.
13
Finally, we found no difference between wild-type and mutant cells in transformation efficiency, suggesting neither mutation inhibits Type IV pilus retraction.
14
Although the mechanism of pilus biogenesis is well characterized, how the usher itself is assembled at the outer membrane is unclear.
15
This study aims to detect phylogenetic inconsistency in CPS genes and pilus islands in GBSs and to explore its relationship with invasiveness.
16
One of the mutations affected a gene encoding a conserved bacterial response regulator, PilR, which is commonly associated with type IV pilus synthesis.
