Iron Oxidation by a Fused Cytochrome-Porin Common to Diverse Iron-Oxidizing Bacteria

mBio, 2021
Iron (Fe) oxidation is one of Earth’s major biogeochemical processes, key to weathering, soil formation, water quality, and corrosion. However, our understanding of microbial contribution is limited by incomplete knowledge of microbial iron oxidation ...

Toxicomicrobiomics: The Human Microbiome vs. Pharmaceutical, Dietary, and Environmental Xenobiotics

Frontiers in Pharmacology, 2020
The harmful impact of xenobiotics on the environment and human health is being more widely recognized; yet, inter- and intraindividual genetic variations among humans modulate the extent of harm, mostly through modulating the outcome of xenobiotic ...

Methane-Dependent Extracellular Electron Transfer at the Bioanode by the Anaerobic Archaeal Methanotroph “Candidatus Methanoperedens”

Frontiers in Microbiology, 2022
Anaerobic methanotrophic (ANME) archaea have recently been reported to be capable of using insoluble extracellular electron acceptors via extracellular electron transfer (EET).

Redox linked flavin sites in extracellular decaheme proteins involved in microbe-mineral electron transfer [PDF]

, 2015
Extracellular microbe-mineral electron transfer is a major driving force for the oxidation of organic carbon in many subsurface environments. Extracellular multi-heme cytochromes of the Shewenella genus play a major role in this process but the mechanism

The relay network of Geobacter biofilms [PDF]

, 2018
While actual models explaining electron conduction in electricity producing biofilms have evolved separately to apparent irreconcilable conceptual positions, finding cytochrome complexes in the external matrix of Geobacter biofilms supports the proposal ...

Membrane-attached mammalian cytochromes P450: An overview of the membrane's effects on structure, drug binding, and interactions with redox partners.

Journal of Inorganic Biochemistry, 2018
Mammalian cytochromes P450 are an important class of enzymes involved in the biotransformation of many endo- and exogenous compounds. Cytochrome P450 isoforms are attached to the membrane of the endoplasmic reticulum or mitochondria, and their catalytic ...

Influence of dough freezing on Saccharomyces cerevisiae metabolism [PDF]

Zbornik Matice Srpske za Prirodne Nauke, 2007
The need to freeze dough is increasing in bakery production. Frozen dough can be stored for a long time without quality change. The capacity of bakery production can be increased in this way, and in the same time, the night shifts can be decreased. Yeast

Multi-heme cytochromes provide a pathway for survival in energy-limited environments

Science Advances, 2018
Widely distributed outer-membrane cytochromes enable sulfur-reducing bacteria to obtain energy from solid electron donors. Bacterial reduction of oxidized sulfur species (OSS) is critical for energy production in anaerobic marine subsurfaces.

A dedicated haem lyase is required for the maturation of a novel bacterial cytochrome c with unconventional covalent haem binding [PDF]

, 2007
In bacterial c-type cytochromes, the haem cofactor is covalently attached via two cysteine residues organized in a haem c-binding motif. Here, a novel octa-haem c protein, MccA, is described that contains only seven conventional haem c-binding motifs ...
