A molecular conveyor belt-associated protein controls the rotational direction of the bacterial type 9 secretion system | mBio The type 9 secretion system (T9SS) is fundamental to bacterial gliding motility, pathogenesis, and surface colonization. Our findings reveal that the C-terminal region of the conveyor belt-associated protein GldJ functions as a molecular switch which is ...

PorA of the Type IX Secretion Is a Ligand of the PorXY Two‐Component Regulatory System in Porphyromonas gingivalis Porphyromonas gingivalis exports several virulent proteins, including gingipain proteinases, via the type 9 secretion system. Expression of several T9SS component proteins is regulated by the PorA-Po...

The C-terminal domain of Porphyromonas gingivalis type IX secretion system (T9SS) cargo protein (PorA) plays a dual role: as a secretion signal directing the secretion of PorA and as a positive regulator of T9SS.
