Electron transfer pathways in a multiheme cytochrome MtrF [PDF]
In MtrF, an outer-membrane multiheme cytochrome, the 10 heme groups are arranged in heme binding domains II and IV along the pseudo-C2 axis, forming the electron transfer (ET) pathways. Previous reports based on molecular dynamics simulations showed that

The modular evolution of multiheme cytochromes c bucks the general trend observed in most proteins
Abstract Multiheme cytochromes c are versatile enzymes which contribute to key steps in diverse biogeochemical cycles of chemical elements such as nitrogen, iron, and sulfur, and are also key players in microbial electrochemical technologies. Understanding how they evolved offers a blueprint on how nature tuned their sequence and heme c cofactors to ...

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

Advancing the Resolution of the Sulfur Compound Disproportionation Puzzle in Dissulfuribacter Thermophilus S69ᵀ Through Quantitative Label-Free Comparative Proteomics. [PDF]
To date, only three microorganisms have been functionally characterised for sulfur disproportionation. Our work identifies a fourth example and provides novel proteomic insights into its underlying pathways. These findings advance our understanding of microbial sulfur catabolism and highlight the ecological role of D.

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