Cell surface differences within the genus Methanosarcina shape interactions with the extracellular environment [PDF]

Journal of Bacteriology
Methanosarcina are metabolically versatile methanogenic archaea that can perform extracellular electron transfer (EET), with important ecological and biotechnological implications.

Ultrafast Light-Driven Electron Transfer in a Ru(II)tris(bipyridine)-Labelled Multiheme Cytochrome [PDF]

Journal of the American Chemical Society, 2019
Multiheme cytochromes attract much attention for their electron transport properties. These proteins conduct electrons across bacterial cell walls, along extracellular filaments, and when purified can serve as bionanoelectronic junctions.

Geobacter sulfurreducens Extracellular Multiheme Cytochrome PgcA Facilitates Respiration to Fe(III) Oxides But Not Electrodes [PDF]

Frontiers in Microbiology, 2017
Extracellular cytochromes are hypothesized to facilitate the final steps of electron transfer between the outer membrane of the metal-reducing bacterium Geobacter sulfurreducens and solid-phase electron acceptors such as metal oxides and electrode ...

Crucial roles of intracellular cyclic di-GMP in impacting the genes important for extracellular electron transfer by Geobacter metallireducens [PDF]

Applied and Environmental Microbiology
To investigate the roles of intracellular c-di-GMP in bacterial extracellular electron transfer (EET), three Geobacter metallireducens strains with high (Gme-H), intermediate (Gme-C), and low (Gme-L) intracellular levels of c-di-GMP were constructed via ...

50 Years of Giese Reaction - a Personal View. [PDF]

Angew Chem Int Ed Engl
The Giese‐Reaction celebrates its 50. Birthday, it is a cyclic radical chain reaction centered around C,C‐bond formation in a three component synthesis. This minireview speaks about the birth of the name‐reaction, explains how the complete understanding of its reaction mechanism stimulates new methods in organic synthesis, and why it can proceed in ...

Do multiheme cytochromes containing close-packed heme groups have a band structure formed from the heme π and π∗ orbitals? [PDF]

Current Opinion in Electrochemistry
Multiheme cytochromes (MHCs) are bacterial electron-transfer proteins. We show from optical spectra and calculations that some of these cytochromes probably contain occupied and unoccupied bands formed from heme π and π∗ orbitals that span the protein ...

Tunneling-to-Hopping Transition in Multiheme Cytochrome Bioelectronic Junctions

The Journal of Physical Chemistry Letters, 2023
Multiheme cytochromes (MHCs) have attracted much interest for use in nanobioelectronic junctions due to their high electronic conductances. Recent measurements on dry MHC junctions suggested that a coherent tunneling mechanism is operative over surprisingly long long distances (>3 nm), which challenges our understanding of coherent transport phenomena.
