The Bacteroidetes phylum is renowned for its ability to degrade a wide range of complex
carbohydrates, a trait that has enabled its dominance in many diverse environments. The …

The anaerobic Gram-negative bacterium Porphyromonas gingivalis is considered the
keystone of periodontitis diseases, a set of inflammatory conditions that affects the tissues …

The type IX secretion system (T9SS) is specific to the Bacteroidetes phylum. Porphyromonas
gingivalis, a keystone pathogen for periodontitis, utilises the T9SS to transport many proteins …

Three classes of ion-driven protein motors have been identified to date: ATP synthase, the
bacterial flagellar motor and a proton-driven motor that powers gliding motility and the type 9 …

The Porphyromonas gingivalis type IX secretion system (T9SS) promotes periodontal
disease by secreting gingipains and other virulence factors. By in situ cryoelectron …

Porphyromonas, Tannerella, and Prevotella species found in severe periodontitis use the
Type IX Secretion System (T9SS) to load their outer membrane surface with an array of …

Motile bacteria usually rely on external apparatus like flagella for swimming or pili for
twitching. By contrast, gliding bacteria do not rely on obvious surface appendages to move …

The Fo ATP synthase, the bacterial flagellar motor, and the bacterial type 9 secretion system
(T9SS) are the three known proton motive force driven biological rotary motors. In this …

Porphyromonas gingivalis is an important human pathogen and also a model organism for
the Bacteroidetes phylum. O-glycosylation has been reported in this phylum with findings …

Porphyromonas gingivalis is a keystone pathogen of the human dysbiotic oral microbiome
that causes severe periodontitis. It employs a type-IX secretion system (T9SS) to shuttle …
