Exploring oxidative stress pathways in Geobacter sulfurreducens: the redox network between MacA peroxidase and triheme periplasmic cytochromes

Frontiers in Microbiology, 2023
The recent reclassification of the strict anaerobe Geobacter sulfurreducens bacterium as aerotolerant brought attention for oxidative stress protection pathways.

Electrochemical Characterization of the Periplasmic PpcA c‐Cytochrome of Geobacter sulfurreducens Reveals Its Affinity for Uranium

ChemElectroChem, 2023
Geobacter bacteria produce conductive pili appendages and an outer membrane‐anchored lipopolysaccharide to immobilize uranium extracellularly. Yet, some radionuclide enters the cell envelope, where is rapidly mineralized by periplasmic c‐cytochromes.

Specialization of the Reiterated Copies of the Heterodimeric Integration Host Factor Genes in Geobacter sulfurreducens

Frontiers in Microbiology, 2021
Integration host factor (IHF) is a widely distributed small heterodimeric protein member of the bacterial Nucleoid-Associated Proteins (NAPs), implicated in multiple DNA regulatory processes.

Phylogenetic incongruence inferred with two mitochondrial genes in Mepraia spp. and Triatoma eratyrusiformis(Hemiptera, Reduviidae)

Genetics and Molecular Biology, 2015
Mitochondrial DNA (mtDNA) is widely used to clarify phylogenetic relationships among and within species, and to determine population structure. Due to the linked nature of mtDNA genes it is expected that different genes will show similar results ...

Age-related modifications in CYP-dependent drug metabolism: role of stress

Frontiers in Endocrinology, 2023
Accumulating clinical evidence indicates extensive inter-individual variations in the effectiveness and adverse effects of standard treatment protocols, which are largely attributed to the multifactorial regulation of the hepatic CYP-dependent drug ...
