Identification and structural characterization functional motifs in the Porphyromonas gingivalis MFA1 short fimbria. [PDF]

, 2021
Porphyromonas gingivalis is a causative agent of periodontal disease, initially colonizes the oral cavity by adhering to commensal streptococci. Adherence requires the interaction of the minor fimbrial protein (Mfa1) of P.

cAMP-independent Crp homolog adds to the multi-layer regulatory network in Porphyromonas gingivalis [PDF]

Frontiers in Cellular and Infection Microbiology
IntroductionPorphyromonas gingivalis encodes three CRP/FNR superfamily proteins: HcpR, PgRsp, and CrpPg, with CrpPg similar to cAMP-sensing proteins but not classified into known families.

In Silico Destruction of Porphyromonas gingivalis Fimbriae by Streptomyces sp. Strain GMY02 [PDF]

BIO Web of Conferences, 2023
Porphyromonas gingivalis, a keystone pathogen in chronic periodontitis, has fimbria as one of the most important virulence factors because it plays a vital role in the pathogenesis of P. gingivalis infection.

Anchoring and length regulation of Porphyromonas gingivalis Mfa1 fimbriae by the downstream gene product Mfa2 [PDF]

Microbiology, 2009
SUMMARY Porphyromonas gingivalis, a causative agent of periodontitis, has at least two types of thin, single-stranded fimbriae termed FimA and Mfa1 (according to the names of major subunits), which can be discriminated by filament length and by the size ...

Identification of a transposon variant of Porphyromonas gingivalis expressing long Mfa1 fimbriae due to mfa2 inactivation.

Journal of Oral Biosciences
OBJECTIVES Fimbriae expressed by Porphyromonas gingivalis, a periodontal pathogen, play a pivotal role in biofilm formation. In the type strain ATCC 33277, Mfa1 fimbriae form short structures anchored to the cell surface by Mfa2, an outer membrane ...

Novel fimbrilin PGN_1808 in Porphyromonas gingivalis. [PDF]

PLoS ONE, 2017
Porphyromonas gingivalis, a periodontopathic gram-negative anaerobic bacterium, generally expresses two types of fimbriae, FimA and Mfa1. However, a novel potential fimbrilin, PGN_1808, in P.

Harnessing the antimicrobial potential of Aegle marmelos against Mfa1 fimbriae in Porphyromonas gingivalis: a new strategy for endodontic therapy.

Cellular and Molecular Biology
Endodontic infections, primarily caused due to microbial invasion into the root canal system, pose a significant challenge to dental health and management due to their complex etiology and resistance to conventional treatment. Porphyromonas gingivalis is
