Four-iron (sulfide) ferredoxin from Bacillus polymyxa.
Ferredoxin from Bacillus polymyxa contains (per mole) four non-heme iron residues, four acid-labile sulfide residues, and four cysteine residues. Its molecular weight is approximately 8,800, and it has an oxidation-reduction potential (E(m)) of -390 mv. It is active as an electron carrier in several ferredoxin-linked enzyme systems.

15 صفحه اولThe Molar Extinction Coefficient of 2,6-dichlorophenol Indophenol.
Widely varying values for the molar extinction coefficient of 2.6-dichlorophenoi indophenol have been reported by various workers 1-9. A possible source of this variation may be the different samples of DCIP used, due either ~o the presence of impurities or to the presence of mixtures of the anhydrous and hydrated forms of DCIP sodium salt. However. failure to realise that DCIP is a weak acid w...
متن کاملInactivation of clostridial ferredoxin and pyruvate-ferredoxin oxidoreductase by sodium nitrite.
Clostridial ferredoxin and pyruvate-ferredoxin oxidoreductase activity was investigated after in vitro or in vivo treatment with sodium nitrite. In vitro treatment of commercially available Clostridium pasteurianum ferredoxin with sodium nitrite inhibited ferredoxin activity. Inhibition of ferredoxin activity increased with increasing levels of sodium nitrite. Ferredoxin was isolated from norma...
متن کاملClostridial iron-sulphur proteins.
Iron-sulfur proteins are ubiquitous catalysts of a wide range of biological reactions, and are particularly abundant in clostridia which lack the ability to synthesize hemes. The development of research on these metalloproteins has therefore been strongly associated with biochemical investigations of clostridial metabolism. Major breakthroughs in the field, from the first isolation of an iron-s...
