Protein

Tungsten-containing aldehyde ferredoxin oxidoreductase

Gene

aor

Organism
Pyrococcus furiosus (strain ATCC 43587 / DSM 3638 / JCM 8422 / Vc1)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the oxidation of aldehydes to their corresponding carboxylic acids. May have a pyroglycolytic (saccharolytic) role.

Miscellaneous

A significant amount of formaldehyde ferredoxin oxidoreductase activity has been observed.

Catalytic activityi

An aldehyde + H2O + 2 oxidized ferredoxin = a carboxylate + 2 H+ + 2 reduced ferredoxin.

Cofactori

Protein has several cofactor binding sites:

Enzyme regulationi

Inhibited by arsenite, iodoacetate and cyanide.

Kineticsi

Significant activity only with aliphatic and aromatic aldehydes and only at low concentration (0.5 mM).
  1. KM=0.72 mM for formaldehyde1 Publication
  1. Vmax=295 µmol/min/mg enzyme with formaldehyde as substrate1 Publication

pH dependencei

Optimum pH is above 10.1 Publication

Temperature dependencei

Optimum temperature is above 90 degrees Celsius.1 Publication
