No sequence similarities were found, however, between the α-subunits of the enzyme from A. fulgidus and the heterodimeric pyruvate: ferredoxin oxidoreductase from Halobacterium halobium . 展开 关键词: Archaea Archaeoglobus Dissimilatory sulfate reduction Hyperthermophiles Pyruvate: ferredoxin (flavodoxin) ...
Pyruvate:ferredoxin (flavodoxin) oxidoreductase (PFO, EC 1.2.7.1) catalyses the oxidative cleavage of pyruvate and coenzyme A to acetylcoenzyme A and CO 2 with the simultaneous reduction of ferredoxin or flavodoxin. PFO occurs in anaerobes and in some aerobic archaea and bacteria. For cyanobacteria...
Pyruvate:ferredoxin (flavodoxin) oxidoreductase (POR) was purified 3050-fold to apparent homogeneity from the photosynthetic bacterium Rhodobacter capsulatus using ion-exchange, Reactive Red, and gel filtration chromatography. The isolated enzyme was sensitive to dilution and oxygen (especially when in ...
4.1 Pyruvate:ferredoxin oxidoreductase (PFOR) The non-redox iron-sulfur clusters discussed above are vulnerable to superoxide and H2O2, which must directly bind iron to oxidize it. In contrast, these ROS cannot damage clusters that are buried in polypeptide—which is true of most clusters that ar...
Pyruvate: ferredoxin oxidoreductase (POR; EC 1.2.7.1) catalyzes the thiamine pyrophosphate-dependent oxidative decarboxylation of pyruvate to form acetyl-CoA and CO2. The thermophilic, obligate chemolithoautotrophic hydrogen-oxidizing bacterium, Hydrogenobacter thermophilus TK-6, assimilates CO2 via the...

Central to anaerobic energy metabolism in many unicellular eukaryotes (protists) is pyruvate:ferredoxin oxidoreductase (PFO), which decarboxylates pyruvate and forms acetyl-coenzyme A with concomitant reduction of low-potential ferredoxins or flavodoxins. Here, we report the biochemical properties of ...
The pyruvate-dependent enzyme was identified as CoA-acetylating pyruvate; flavodoxin (ferredoxin) oxidoreductase. Its catalytic properties in the forward. reverse, and the 14 CO 2 -pyruvate exchange reaction are reported. The dihydro form of flavodoxin was characterized as the particular species ...
