Role of Mfa5 in Expression of Mfa1 Fimbriae in Porphyromonas gingivalis [PDF]

Journal of Dental Research, 2016
Fimbriae are protein-based filamentous appendages that protrude from the bacterial cell surface and facilitate host adhesion. Two types of fimbriae, FimA and Mfa1, of the periodontal pathogen Porphyromonas gingivalis are responsible for adherence to other bacteria and to host cells in the oral cavity. Both fimbrial forms are composed of 5 proteins, but

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.

Structural and functional characterization of shaft, anchor, and tip proteins of the Mfa1 fimbria from the periodontal pathogen Porphyromonas gingivalis [PDF]

Scientific Reports, 2018
Very 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 ...

Identification and Characterization of MFA1, the Gene Encoding Candida albicansa-Factor Pheromone [PDF]

Eukaryotic Cell, 2007
In the opaque state, MTLa and MTLα strains of Candida albicans are able to mate, and this mating is directed by a pheromone-mediated signaling process. We have used comparisons of genome sequences to identify a C.

Virulence diversity among Porphyromonas gingivalis strains: a review of genetic factors [PDF]

Journal of Oral Microbiology
Background Porphyromonas gingivalis (P. gingivalis) is a Gram-negative anaerobic bacterium and a keystone pathogen in chronic periodontitis. Beyond oral disease, it has been implicated in systemic conditions, including cardiovascular disease, type 2 ...

Mouse fetal antigen 1 (mFA1), the circulating gene product of mdlk, pref-1 and SCP-1: isolation, characterization and biology. [PDF]

Journal of reproduction and fertility, 1996
The mouse homologue to human fetal antigen 1 (hFA1) was purified from mouse amniotic fluid by cation exchange chromatography and immunospecific affinity chromatography. Mouse FA1 (mFA1) is a single chain glycoprotein with an M(r) of 42-50 kDa (SDS-PAGE). The N-terminal amino acid sequence (39 residues) revealed 74% identity to hFA1 and 100% identity to

Glycosylation analysis and protein structure determination of murine fetal antigen 1 (mFA1)--the circulating gene product of the delta-like protein (dlk), preadipocyte factor 1 (Pref-1) and stromal-cell-derived protein 1 (SCP-1) cDNAs. [PDF]

European Journal of Biochemistry, 1997
By means of sequence analysis, murine fetal antigen 1 (mFAl) isolated from Mus musculus amniotic fluid was shown to be the circulating protein of the δ‐like protein, stromal‐cell‐derived protein 1 (SCP‐1) and preadipocyte factor 1 (Pref‐1) gene products. The protein contains 36 cysteine residues arranged in six epidermal‐growth‐factor‐like domains. The

Giant honeybees (Apis dorsata) trade off defensiveness against periodic mass flight activity. [PDF]

PLoS ONE
The giant honeybee Apis dorsata (Fabricius, 1793) is an evolutionarily ancient species that builds its nests in the open. The nest consists of a single honeycomb covered with the bee curtain which are several layers of worker bees that remain almost ...
