Large-scale prediction of outer-membrane multiheme cytochromes uncovers hidden diversity of electroactive bacteria and underlying pathways [PDF]

Frontiers in Microbiology
Multi-heme cytochromes (MHCs), together with accessory proteins like porins and periplasmic cytochromes, enable microbes to transport electrons between the cytoplasmic membrane and extracellular substrates (e.g., minerals, electrodes, other cells ...

Increased mutation rates and diversity are dominant features of Geobacter multiheme cytochromes [PDF]

mBio
Multiheme cytochromes (MHCs) are the central catalysts of extracellular electron transfer and are uniquely abundant in the genomes of model Fe(III)-reducing organisms like Geobacter sulfurreducens.

Iron or sulfur respiration—an adaptive choice determining the fitness of a natronophilic bacterium Dethiobacter alkaliphilus in geochemically contrasting environments [PDF]

Frontiers in Microbiology, 2023
Haloalkaliphilic microorganisms are double extremophiles functioning optimally at high salinity and pH. Their typical habitats are soda lakes, geologically ancient yet widespread ecosystems supposed to harbor relict microbial communities.

Electron transport across the cell envelope via multiheme c-type cytochromes in Geobacter sulfurreducens [PDF]

Frontiers in Chemistry
Extracellular electron transfer (EET) enables certain microorganisms to respire using soluble and insoluble extracellular electron acceptors by transporting electrons across the cell envelope. Among these, G. sulfurreducens serves as a model organism for

Microbial magnetite oxidation via MtoAB porin-multiheme cytochrome complex in Sideroxydans lithotrophicus ES-1 [PDF]

Applied and Environmental Microbiology
Most of Earth’s iron is mineral-bound, but it is unclear how and to what extent iron-oxidizing microbes can use solid minerals as electron donors. A prime candidate for studying mineral-oxidizing growth and pathways is Sideroxydans lithotrophicus ES-1, a

Genetic Manipulation of Desulfovibrio ferrophilus and Evaluation of Fe(III) Oxide Reduction Mechanisms [PDF]

Microbiology Spectrum, 2022
The sulfate-reducing microbe Desulfovibrio ferrophilus is of interest due to its relatively rare ability to also grow with Fe(III) oxide as an electron acceptor and its rapid corrosion of metallic iron. Previous studies have suggested multiple agents for

Molecular Mechanisms of Microbial Extracellular Electron Transfer: The Importance of Multiheme Cytochromes

Frontiers in Bioscience, 2022
Extracellular electron transfer is a key metabolic process of many organisms that enables them to exchange electrons with extracellular electron donors/acceptors.
