Characterization of superoxide dismutase from Actinomyces
The anaerobes Actinomyces naeslundii, A. odontolyticus and Actinomyces strain ii E1S.25D produce a Mn-containing superoxide dismutase (MnSOD). Actinomyces, once classified as yeast based on their morphology, are saprophytic organisms found among the normal flora of the mouth but can act as …

Assembly and Display of Surface Proteins In Actinomyces Oris
… of the oral biofilm, the actinobacterium <em>Actinomyces oris</em> utilizes cell wall anchored proteins and glycoconjugates to initiate adherence to host surfaces, recruit additional bacterial species that could not bind otherwise, and maintain the structural integrity of the oral biofilm. In …

Salivary Reduction of Dietary Nitrate
… reductase activity from the anaerobic bacteria (Actinomyces and Veillonella) species found in the tongue’s cleft. Preliminary genomic analyses of these species indicate the lack of nitrite (NO2-) reductase ortholog genes suggesting dissimilatory NO3- reduction. The goal of Aim 1 of this research …

Insights Into The Reactivation, Regulation and Essentiality of Oxidative Protein Folding Pathways In Actinobacteria
… the Gram-positive actinobacterial pathogens <em>Actinomyces oris </em>and <em>Corynebacterium diphtheriae</em> oxidative protein folding is catalyzed by the primary thiol-disulfide oxidoreductase MdbA. MdbA is required for assembly of adhesive pilus, which mediate receptor-dependent bacterial …

THE EFFECT OF INDOOR TOTAL SUSPENDED PARTICLES (TSP) ON THE HUMAN UPPER RESPIRATORY SYSTEM: FROM THE MICROBIOME TO HERV METHYLATION
… that at low abundance of Cutibacterium acnes and Actinomyces naeslundii, indoor TSP exposure is associated with increased methylation of HERV-W. This HERV sequence was previously found to be hypermethylated in response to air pollution exposure. In conclusion, this evidence indicates that indoor …

Oxidative Protein Folding Pathways In Gram-Positive Actinobacteria
<p>Disulfide bonds are important for the stability of many secreted proteins. These covalent linkages, which result from the oxidation of neighboring cysteine (Cys) residues, are often rate-limiting steps for protein folding and maturation. Disulfide bond formation is restricted to extracellular …
