Comments
  • FUNCTION: Catalyzes the ferredoxin-dependent oxidative decarboxylation of arylpyruvates (By similarity).
  • CATALYTIC ACTIVITY: (Indol-3-yl)pyruvate + CoA + 2 oxidized ferredoxin = S-2-(indol-3-yl)acetyl-CoA + CO2 + 2 reduced ferredoxin + H+.
  • SUBUNIT: Heterodimer of the iorA and iorB subunits.
