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

open access: yesJournal of Oral Biosciences
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 protein involved in regulation of fimbrial length.

Purification of Native Mfa1 Fimbriae from Porphyromonas gingivalis

2020
Fimbriae 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, 2015
The 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.

Draft Genome Sequence of Porphyromonas gingivalis Strain Ando Expressing a 53-Kilodalton-Type Fimbrilin Variant of Mfa1 Fimbriae [PDF]

open access: yesGenome 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.

Expression of MFA1 and STE6 is sufficient for mating type-independent secretion of yeast a-factor, but not mating competence

Current Genetics, 1999
The yeast a-factor mating peptide and its transporter Ste6 are normally expressed only in MATa haploid cells. The a-factor is initially produced as a 36- or 38-residue peptide precursor and must undergo extensive post-translational processing to produce an active 12 amino-acid lipopeptide.

Localization and function of the accessory protein Mfa3 in Porphyromonas gingivalis Mfa1 fimbriae

Molecular Oral Microbiology, 2013
SummaryThe fimbriae of Porphyromonas gingivalis, the causative agent of periodontitis, have been implicated in various aspects of pathogenicity, such as colonization, adhesion and aggregation. Porphyromonas gingivalis ATCC 33277 has two adhesins comprised of the FimA and Mfa1 fimbriae.

Mutational analysis of genes determining antagonism of Alcaligenes sp. strain MFA1against the phytopathogenic fungus Fusarium oxysporum

Canadian Journal of Microbiology, 1992
Alcaligenes sp. strain MFA1 inhibits microconidial germination and germination-tube elongation of Fusarium oxysporum f.sp. dianthi and reduces the severity of fusarium wilt of carnation, presumably as a result of its production of a siderophore (G.Y. Yuen and M.N. Schroth. 1986. Phytopathology, 76: 171–176).
