Multi-heme Cytochromes in Shewanella oneidensis MR-1:Structures, functions and opportunities [PDF]
Journal of the Royal Society Interface, 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 ...

The Arabidopsis Book, 2011 There are 244 cytochrome P450 genes (and 28 pseudogenes) in the Arabidopsis genome. P450s thus form one of the largest gene families in plants. Contrary to what was initially thought, this family diversification results in very limited functional redundancy and seems to mirror the complexity of plant metabolism.

The Role of Cytochromes P450 in Infection
Frontiers in Immunology, 2018 Cytochromes are expressed in many different tissues of the human body. They are found mostly in intestinal and hepatic tissues. Cytochromes P450 (CYPs) are enzymes that oxidize substances using iron and are able to metabolize a large variety of ...

Multi-heme cytochromes provide a pathway for survival in energy-limited environments
Science Advances, 2018 Widely distributed outer-membrane cytochromes enable sulfur-reducing bacteria to obtain energy from solid electron donors. Bacterial reduction of oxidized sulfur species (OSS) is critical for energy production in anaerobic marine subsurfaces.

Natural Product Reports, 2018 Covering: 2000 up to 2018 The cytochromes P450 (P450s) are a superfamily of heme-containing monooxygenases that perform diverse catalytic roles in many species, including bacteria. The P450 superfamily is widely known for the hydroxylation of unactivated

Molecular Microbiology, 2007 Dissimilatory reduction of metal (e.g. Fe, Mn) (hydr)oxides represents a challenge for microorganisms, as their cell envelopes are impermeable to metal (hydr)oxides that are poorly soluble in water.

Label-free photoacoustic microscopy of cytochromes [PDF]
Journal of Biomedical Optics, 2013 Photoacoustic microscopy (PAM) has achieved submicron lateral resolution in showing subcellular structures; however, relatively few endogenous subcellular contrasts have so far been imaged. Given that the hemeprotein, mostly cytochromes in general cells,

PLoS ONE, 2014 Confocal Resonance Raman Microscopy (CRRM) was used to probe variations of redox state of c-type cytochromes embedded in living mixed-culture electroactive biofilms exposed to different electrode polarizations, under potentiostatic and potentiodynamic ...

In situ Raman study of redox state changes of mitochondrial cytochromes in a perfused rat heart. [PDF]
PLoS ONE, 2013 We developed a Raman spectroscopy-based approach for simultaneous study of redox changes in c-and b-type cytochromes and for a semiquantitative estimation of the amount of oxygenated myoglobin in a perfused rat heart.

Electron transport across the cell envelope via multiheme c-type cytochromes in Geobacter sulfurreducens [PDF]
Frontiers in ChemistryExtracellular electron transfer (EET) enables certain microorganisms to respire using soluble and insoluble extracellular electron acceptors by transporting electrons across the cell envelope. Among these, G. sulfurreducens serves as a model organism for
