Roles of c-type cytochromes in respiration in Neisseria meningitidis [PDF]

Microbiology, 2008
Three c-type cytochromes were identified in Neisseria meningitidis, based on predictions from genome sequences, that were hypothesized to be involved in electron transport to terminal electron acceptor reductases for oxygen (the cytochrome cbb(3) oxidase) and nitrite (the nitrite reductase, AniA).

Effect of pH on the thermostability and redox properties of cytochrome c552 from Wolinella succinogenes

Frontiers in Chemical Biology
Cytochrome c552 from Wolinella succinogenes is one of the few examples of a low reduction potential class I c-type cytochrome with a mixture of high/low spin state populations observed in its visible spectrum.

The Met80Ala and Tyr67His/Met80Ala mutants of human cytochrome cshed light on the reciprocal role of Met80 and Tyr67 in regulating ligand access into the heme pocket. [PDF]

, 2017
The spectroscopic and functional properties of the single Met80Ala and double Tyr67His/Met80Ala mutants of human cytochrome c have been investigated in their ferric and ferrous forms, and in the presence of different ligands, in order to clarify the ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

A Membrane-Bound Cytochrome Enables Methanosarcina acetivorans To Conserve Energy from Extracellular Electron Transfer

mBio, 2019
Extracellular electron exchange in Methanosarcina species and closely related Archaea plays an important role in the global carbon cycle and enhances the speed and stability of anaerobic digestion by facilitating efficient syntrophic interactions.

Constructing a man-made c-type cytochrome maquette in vivo:electron transfer, oxygen transport and conversion to a photoactive light harvesting maquette [PDF]

, 2014
The successful use of man-made proteins to advance synthetic biology requires both the fabrication of functional artificial proteins in a living environment, and the ability of these proteins to interact productively with other proteins and substrates in

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

K-shell Analysis Reveals Distinct Functional Parts in an Electron Transfer Network and Its Implications for Extracellular Electron Transfer

Frontiers in Microbiology, 2016
Shewanella oneidensis MR-1 is capable of extracellular electron transfer (EET) and hence has attracted considerable attention. The EET pathways mainly consist of c-type cytochromes, along with some other proteins involved in electron transfer processes ...

Ornithine Lipid is Required for c‐type Cytochrome Biogenesis

The FASEB Journal, 2006
In phototrophic bacteria like Rhodobacter capsulatus (Rc), c‐type cytochrome (cyt) biogenesis is encoded by the ccmABCDEFGHI genes. Using the cyt cbb3 oxidase‐ phenotype, additional required genes were sought. This search yielded mutants that exhibited medium‐dependent photosynthetic growth, and that lacked various c‐type cyts ...
