The RgpB C-terminal domain has a role in attachment of RgpB to the outer membrane and belongs to a novel C-terminal-domain family found in Porphyromonas gingivalis.
Porphyromonas gingivalis produces outer membrane-attached proteins that include the virulence-associated proteinases RgpA and RgpB (Arg-gingipains) and Kgp (Lys-gingipain). We analyzed the P.… Expand

Protein substrates of a novel secretion system are numerous in the Bacteroidetes phylum and have in common a cleavable C-terminal secretion signal, extensive post-translational modification, and…
The secretion of certain proteins in Porphyromonas gingivalis is dependent on a C-terminal domain (CTD). After secretion, the CTD is cleaved prior to extensive modification of the mature protein,… Expand

Major outer membrane proteins and proteolytic processing of RgpA and Kgp of Porphyromonas gingivalis W50.
Porphyromonas gingivalis is an anaerobic, asaccharolytic Gram-negative rod associated with chronic periodontitis. We have undertaken a proteomic study of the outer membrane of P. gingivalis strain… Expand

PG0026 Is the C-terminal Signal Peptidase of a Novel Secretion System of Porphyromonas gingivalis♦
Background: Several virulence factors of Porphyromonas gingivalis have a novel C-terminal signal that directs secretion across the outer membrane. Results: The predicted catalytic amino acid of… Expand

The outer membrane protein LptO is essential for the O‐deacylation of LPS and the co‐ordinated secretion and attachment of A‐LPS and CTD proteins in Porphyromonas gingivalis
Protein substrates of a novel secretion system of Porphyromonas gingivalis contain a conserved C‐terminal domain (CTD) essential for secretion and attachment to the cell surface. Inactivation of lptO… Expand

Identification of a New Membrane-associated Protein That Influences Transport/Maturation of Gingipains and Adhesins of Porphyromonas gingivalis*
The dual membrane envelopes of Gram-negative bacteria provide two barriers of unlike nature that regulate the transport of molecules into and out of organisms. Organisms have developed several… Expand

A Novel Porphyromonas gingivalis FeoB Plays a Role in Manganese Accumulation*
FeoB is an atypical transporter that has been shown to exclusively mediate ferrous ion transport in some bacteria. Unusually the genome of the periodontal pathogen Porphyromonas gingivalis has two… Expand

Mass spectrometric analyses of peptides and proteins in human gingival crevicular fluid.
Gingival crevicular fluid (GCF) is a pathophysiological fluid that flows into the oral cavity. Human GCF was collected using sterile glass microcapillary tubes from inflamed periodontal sites in… Expand

Porphyromonas gingivalis outer membrane vesicles exclusively contain outer membrane and periplasmic proteins and carry a cargo enriched with virulence factors.
Porphyromonas gingivalis, a keystone pathogen associated with chronic periodontitis, produces outer membrane vesicles (OMVs) that carry a cargo of virulence factors. In this study, the proteome of… Expand

An Immune Response Directed to Proteinase and Adhesin Functional Epitopes Protects against Porphyromonas gingivalis-Induced Periodontal Bone Loss1
Porphyromonas gingivalis, a pathogen associated with periodontitis, bound to fibrinogen, fibronectin, hemoglobin, and collagen type V with a similar profile to that of its major virulence factor, the… Expand
