The electron transport chains of Neisseria meningitidis [PDF]

, 2007
Neisseria meningitidis contains c-type and b-type cytochromes. Oxidation of c-type and b-type cytochromes by oxygen was observed in both cells grown under aerobic and denitrifying conditions, whereas oxidation of cytochromes by nitrite was only seen in ...

Molecular biology of Bacillus subtilis cytochromes

, 1992
Bacillus subtilis cells must have cytochromes for growth and can synthesize cytochromes of a-, b-, c-, d-, and o-types. After a long lag, our knowledge of the structure, genetics and specific role for these cytochromes is now growing exponentially as the

A periplasmic and extracellular c-type cytochrome of Geobacter sulfurreducens acts as a ferric iron reductase and as an electron carrier to other acceptors or to partner bacteria

, 1998
An extracellular electron carrier excreted into the growth medium by cells of Geobacter sulfurreducens was identified as a c-type cytochrome. The cytochrome was found to be distributed in about equal amounts in the membrane fraction, the periplasmic ...

Geobacter sulfurreducens Extracellular Multiheme Cytochrome PgcA Facilitates Respiration to Fe(III) Oxides But Not Electrodes

Frontiers in Microbiology, 2017
Extracellular cytochromes are hypothesized to facilitate the final steps of electron transfer between the outer membrane of the metal-reducing bacterium Geobacter sulfurreducens and solid-phase electron acceptors such as metal oxides and electrode ...

In situ determination of the reduction levels of cytochromes b and c in growing bacteria: a case study with N2-fixing Azorhizobium caulinodans

, 1993
The determination of the in situ reduction levels of cytochromes b and c in growing bacteria is achieved by coupling a chemostat with a dual wavelength spectrophotometer. Visible light absorption spectra of cytochromes present in bacterial cells actively

Soluble cytochromes from the marine methanotroph Methylomonas sp. strain A4 [PDF]

, 1990
Soluble c-type cytochromes are central to metabolism of C1 compounds in methylotrophic bacteria. In order to characterize the role of c-type cytochromes in methane-utilizing bacteria (methanotrophs), we have purified four different cytochromes ...

Biochemical requirements for the maturation of mitochondrial c-type cytochromes

, 2009
Cytochromes c are metalloproteins that function in electron transfer reactions and contain a heme moiety covalently attached via thioether linkages between the co-factor and a CXXCH motif in the protein.

CCS2, an Octatricopeptide-Repeat Protein, Is Required for Plastid Cytochrome c Assembly in the Green Alga Chlamydomonas reinhardtii

Frontiers in Plant Science, 2017
In bacteria and energy generating organelles, c-type cytochromes are a class of universal electron carriers with a heme cofactor covalently linked via one or two thioether bonds to a heme binding site. The covalent attachment of heme to apocytochromes is

Purification and characterization of low potential c cytochromes from Desulfovibrio desulfuricans membranes

, 1986
Desulfovibrio desulfuricans grown in a lactate-sulfate medium produces, in addition to soluble cytochromes, c-type cytochromes which appear to be integral membrane proteins.

Multi-heme cytochromes—new structures, new chemistry

, 2005
Heme is one of the most pervasive cofactors in nature and the c-type cytochromes represent one of the largest families of heme-containing proteins. Recent progress in bacterial genomic analysis has revealed a vast range of genes encoding novel c-type ...
