A New Paradigm of Multiheme Cytochrome Evolution by Grafting and Pruning Protein Modules [PDF]
Molecular Biology and Evolution, 2022 Abstract Multiheme cytochromes play key roles in diverse biogeochemical cycles, but understanding the origin and evolution of these proteins is a challenge due to their ancient origin and complex structure. Up until now, the evolution of multiheme cytochromes composed by multiple redox modules in a single polypeptide chain was ...

Isotopic labeling of c-type multiheme cytochromes overexpressed in E. coli
Protein Expression and Purification, 2008Progresses made in bacterial genome sequencing show a remarkable profusion of multiheme c-type cytochromes in many bacteria, highlighting the importance of these proteins in different cellular events. However, the characterization of multiheme cytochromes has been significantly retarded by the numerous experimental challenges encountered by researchers

Analysis of the residual alignment of a paramagnetic multiheme cytochrome by NMR
Chemical Communications, 2014Residual dipolar couplings measured by NMR spectroscopy reveal that the rhombicity of the electronic structure of low-spin paramagnetic hemes determines their relative contribution to the preferential orientation of a protein with multiple hemes when placed in a strong magnetic field.

The multiheme cytochrome MtrA enables microbial respiration by transferring electrons across the outer membrane to extracellular electron acceptors. While structural studies have identified residues that mediate MtrA binding to hemes and to other cytochromes that facilitate extracellular electron transfer (EET), the relative ...

A systematic investigation of multiheme c-type cytochromes in prokaryotes
JBIC Journal of Biological Inorganic Chemistry, 2010Multiheme c-type cytochromes (MHCs) are metalloproteins that can play various biochemical roles, including enzymatic activity and electron transfer. As electron transfer proteins, the presence of multiple heme cofactors in the vicinity allows electrons to rapidly travel relatively long distances.

Structural and functional insights of GSU0105, a unique multiheme cytochrome from G. sulfurreducens
Biophysical Journal, 2021Geobacter sulfurreducens possesses over 100 cytochromes that assure an effective electron transfer to the cell exterior. The most abundant group of cytochromes in this microorganism is the PpcA family, composed of five periplasmic triheme cytochromes with high structural homology and identical heme coordination (His-His).
