Several new structures of three types of protein complexes, obtained by cryo-electron
microscopy (cryo-EM) and published between 2019 and 2021, identify a new family of …

The type IX secretion system (T9SS) is a multiprotein machine distributed in Bacteroidota
and responsible for the secretion of various proteins across the outer membrane. Secreted …

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 …

Many bacteria belonging to the phylum Bacteroidetes move on solid surfaces, called gliding
motility. In our previous study with the Bacteroidetes gliding bacterium Flavobacterium …

Secretion systems are protein export machines that enable bacteria to exploit their
environment through the release of protein effectors. The Type 9 Secretion System (T9SS) is …

Porphyromonas gingivalis is a gram-negative oral anaerobic pathogen and is one of the key
causative agents of periodontitis. P. gingivalis utilises a range of virulence factors, including …

The type IX secretion system (T9SS) is a large multi-protein transenvelope complex
distributed into the Bacteroidetes phylum and responsible for the secretion of proteins …

Members of the phylum Bacteroidetes play a key role in the marine carbon cycle through
their degradation of polysaccharides via carbohydrate-active enzymes (CAZymes) and …

Porphyromonas gingivalis is an anaerobic Gram‐negative human oral pathogen highly
associated with the more severe forms of periodontal disease. Porphyromonas gingivalis …

As one of the keystone pathogens of periodontitis, the oral bacterium Porphyromonas
gingivalis produces an array of virulence factors, including a recently identified sialidase …
