Charge transfer through a cytochrome multiheme chain: Theory and simulation
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2014 We study sequential charge transfer within a chain of four heme cofactors located in the c-type cytochrome subunit of the photoreaction center of Rhodopseudomonas viridis from a theoretical perspective. Molecular dynamics simulations of the thermodynamic integration type are used to compute two key energies of Marcus' theory of charge transfer, the ...

Perspectives on Microbial Electron Transfer Networks for Environmental Biotechnology
Frontiers in Microbiology, 2022 The overlap of microbiology and electrochemistry provides plenty of opportunities for a deeper understanding of the redox biogeochemical cycle of natural-abundant elements (like iron, nitrogen, and sulfur) on Earth. The electroactive microorganisms (EAMs)

Archaea catalyze iron-dependent anaerobic oxidation of methane [PDF]
, 2016 Anaerobic oxidation of methane (AOM) is crucial for controlling the emission of this potent greenhouse gas to the atmosphere. Nitrite-, nitrate-, and sulfate-dependent methane oxidation is well-documented, but AOM coupled to the reduction of oxidized ...

Optimizing Electroactive Organisms: The Effect of Orthologous Proteins
Frontiers in Energy Research, 2019 Extracellular electron transfer pathways allow bacteria to transfer electrons from the cell metabolism to extracellular substrates, such as metal oxides in natural environments and electrodes in microbial electrochemical technologies (MET).

Putative Extracellular Electron Transfer in Methanogenic Archaea
Frontiers in Microbiology, 2021 It has been suggested that a few methanogens are capable of extracellular electron transfers. For instance, Methanosarcina barkeri can directly capture electrons from the coexisting microbial cells of other species.

Non-Respiratory Extracellular Electron Transfer Competes with Nitrogenase for Electrons in Rhodopseudomonas Palustris. [PDF]
Adv Sci (Weinh)This study develops a photosynthetic bioelectrochemical nitrogen fixation system for simultaneous nitrogen fixation and current generation using Rhodopseudomonas palustris. Notably, extracellular electron transfer (EET) serves as a redox balancing strategy, suppressing nitrogen fixation by competing with nitrogenase for electrons.

Architecture of the Heme-translocating CcmABCD/E complex required for Cytochrome c maturation
Nature Communications, 2023 Mono- and multiheme cytochromes c are post-translationally matured by the covalent attachment of heme. For this, Escherichia coli employs the most complex type of maturation machineries, the Ccm-system (for cytochrome c maturation).

Molecular Dissection of Bacterial Nanowires
mBio, 2013 The discovery of bacterial conductive structures, termed nanowires, has intrigued scientists for almost a decade. Nanowires enable bacteria to transfer electrons over micrometer distances to extracellular electron acceptors such as insoluble metal oxides
