Mind the gap: diversity and reactivity relationships among multihaem cytochromes of the MtrA/DmsE family [PDF]

, 2012
Shewanella oneidensis MR-1 has the ability to use many external terminal electron acceptors during anaerobic respiration, such as DMSO. The pathway that facilitates this electron transfer includes the decahaem cytochrome DmsE, a paralogue of the MtrA ...

The role of intramolecular interactions in the functional control of multiheme cytochromes c [PDF]

FEBS Letters, 2011
Detailed thermodynamic and structural data measured in soluble monomeric multiheme cytochromes c provided the basis to investigate the functional significance of interactions between redox co‐factors. The steep decay of intramolecular interactions with distance means that close proximity of the redox centers is necessary to modulate the intrinsic ...

Efficient and selective isotopic labeling of hemes to facilitate the study of multiheme proteins

BioTechniques, 2012
Specific isotopic labeling of hemes provides a unique opportunity to characterize the structure and function of heme-proteins. Unfortunately, current methods do not allow efficient labeling in high yields of multiheme cytochromes c, which are of great ...

Comparative genomics reveals electron transfer and syntrophic mechanisms differentiating methanotrophic and methanogenic archaea.

PLoS Biology, 2022
The anaerobic oxidation of methane coupled to sulfate reduction is a microbially mediated process requiring a syntrophic partnership between anaerobic methanotrophic (ANME) archaea and sulfate-reducing bacteria (SRB).

Multi-heme Cytochromes in Shewanella oneidensis MR-1:Structures, functions and opportunities [PDF]

, 2015
Multi-heme cytochromes are employed by a range of microorganisms to transport electrons over distances of up to tens of nanometers. Perhaps the most spectacular utilization of these proteins is in the reduction of extracellular solid substrates ...

Beyond Methane Oxidation: The Protein Landscape of ANME-2a Reveals an Integrated System for Diazotrophy and Membrane Fortification. [PDF]

Environ Microbiol Rep
A protein interaction network of ANME‐2a uncovers a modular blueprint where core methane oxidation is energetically coupled to nitrogen fixation and membrane lipid biosynthesis. This integrated system explains the archaeon's metabolic autonomy and resilience in its extreme deep‐sea niche.

Discovery of a functional, contracted heme-binding motif within a multiheme cytochrome [PDF]

Journal of Biological Chemistry, 2019
Anaerobic ammonium-oxidizing (anammox) bacteria convert nitrite and ammonium via nitric oxide (NO) and hydrazine into dinitrogen gas by using a diverse array of proteins, including numerous c-type cytochromes. Many new catalytic and spectroscopic properties of c-type cytochromes have been unraveled by studies on the biochemical pathways underlying the ...

Multiheme Cytochromes from the Sulfur‐Reducing Bacterium Desulfuromonas Acetoxidans [PDF]

European Journal of Biochemistry, 1997
Two new multiheme cytochromes were isolated from the anaerobic sulfur reducing bacterium Desulfuromonas acetoxidans. They have monomeric molecular masses of 50 and 65 kDa and contain six and eight hemes, respectively. Visible and EPR spectroscopies, in the as‐isolated (oxidised) cytochromes, show the presence of only low‐spin hemes in the 50‐kDa ...
