Porphyromonas gingivalis Mfa1 Induces Chemokine and Cell Adhesion Molecules in Mouse Gingival Fibroblasts via Toll-Like Receptors [PDF]
Journal of Clinical Medicine, 2020 Porphyromonas gingivalis Mfa1 fimbriae are thought to act as adhesion factors and to direct periodontal tissue destruction but their immunomodulatory actions are poorly understood. Here, we investigated the effect of Mfa1 stimulation on the immune and metabolic mechanisms of gingival fibroblasts from periodontal connective tissue.

Porphyromonas gingivalis (Pg) a major periodontal pathogen involved in periodontal disease development and progression. Moreover, Pg has two fimbriae surface proteins (FimA and Mfa1) that are genetically distinct and make-up the fimbrial shaft which in-turn form crucial attachment to oral bacteria and multiple host cells.

Structural and functional characterization of shaft, anchor, and tip proteins of the Mfa1 fimbria from the periodontal pathogen Porphyromonas gingivalis [PDF]
Scientific Reports, 2018 AbstractVery little is known about how fimbriae of Bacteroidetes bacteria are assembled. To shed more light on this process, we solved the crystal structures of the shaft protein Mfa1, the regulatory protein Mfa2, and the tip protein Mfa3 from the periodontal pathogen Porphyromonas gingivalis.

Draft Genome Sequence of Porphyromonas gingivalis Strain Ando Expressing a 53-Kilodalton-Type Fimbrilin Variant of Mfa1 Fimbriae [PDF]
Genome Announcements, 2015 ABSTRACT Periodontopathic Porphyromonas gingivalis strain Ando abundantly expresses a 53-kDa-type Mfa1 fimbria. Here, we report the draft genome sequence of Ando, with a size of 2,229,994 bp, average G+C content of 48.4%, and 1,755 predicted protein-coding sequences.

Purification of Native Mfa1 Fimbriae from Porphyromonas gingivalis
2020Fimbriae of the periodontal pathogen Porphyromonas gingivalis mediate its colonization through associations with other bacteria and host tissues. P. gingivalis generally expresses two distinct fimbrial types, FimA and Mfa1. In P. gingivalis ATCC 33277, FimA fimbriae are present as long filaments easily detached from cells, whereas Mfa1 fimbriae are ...

A Major Fimbrilin Variant of Mfa1 Fimbriae in Porphyromonas gingivalis
Journal of Dental Research, 2015The periodontal pathogen Porphyromonas gingivalis is known to express 2 distinct types of fimbriae: FimA and Mfa1 fimbriae. However, we previously reported that fimbria-like structures were found in a P. gingivalis strain in which neither FimA nor Mfa1 fimbriae were detected. In this study, we identified a major protein in the bacterial lysates of the

Synergistetes strain MFA1 is an asaccharolytic ruminal bacterium isolated based on its ability to degrade fluoroacetate, a plant toxin. The amino acid and peptide requirements of the bacterium were investigated under different culturing conditions. The growth of strain MFA1 and its fluoroacetate degradation rate were enhanced by peptide-rich protein ...
