The interactions of cytochrome c and porphyrin cytochrome c with cytochrome c oxidase. The resting, reduced and pulsed enzymes [PDF]

European Journal of Biochemistry, 1986
Cytochrome c oxidase forms tight binding complexes with the cytochrome c analog, porphyrin cytochrome c. The behaviour of the reduced and pulsed forms of the oxidase with porphyrin cytochrome c have been followed as functions of ionic strength; this behaviour has been compared with that of the resting oxidase [Kornblatt, Hui Bon Hoa and English (1984 ...

Formation of nanoscale elemental silver particles via enzymatic reduction by Geobacter sulfurreducens

, 2008
Geobacter sulfurreducens reduced Ag(I) (as insoluble AgCl or Ag+ ions), via a mechanism involving c-type cytochromes, precipitating extracellular nanoscale Ag(0). These results extend the range of metals known to be reduced by Geobacter species and offer

The influence of carboxymethylcellulose, xanthan and guar-gum addition in bread dough before freezing on metabolism and viability of Saccharomyces cerevisiae [PDF]

Acta Periodica Technologica, 2009
Doughs were prepared with different concentrations of carboxymethylcellulose, xanthan, and guar-gum (0.1, 0.2 and 0.3% in doughs), freezed at -20°C and analyzed after 0, 7, 15 and 30 days. Pure Saccharomyces cerevisiae culture was isolated from dough and

Redox Thermodynamics of Cytochromes c Subjected to Urea Induced Unfolding [PDF]

, 2009
The thermodynamics of the electron transfer (ET) process for beef heart and yeast cytochromes c and the Lys72Ala/Lys73Ala/Lys79Ala mutant of the latter species subjected to progressive urea-induced unfolding was determined electrochemically.

The presence of two cytochromes b in the facultative methylotroph Pseudomonas AM1

, 1979
Two cytochromes b with absorption maxima at 555 and 562 nm and differing in their mid-point redox potentials are synthesized in Pseudomonas AM1 during growth on methanol or succinate in batch culture, or in NH4+-limited or carbon-limited continuous ...

Cytochromes P460 and c′-beta; A new family of high-spin cytochromes c

, 2007
Cytochromes-P460 of Nitrosomonas europaea and Methylococcus capsulatus (Bath), and the cytochrome c′ of M. capsulatus, believed to be involved in binding or transformation of N-oxides, are shown to represent an evolutionarily related new family of ...

In vitro studies on cytochrome c biogenesis

, 2003
C-type cytochromes are essential for almost all organisms and are mainly involved in electron transport; they are characterised by the covalent attachment of heme to protein through two thioether bonds to a CXXCH peptide motif.
