CC   -!- FUNCTION: Catalyzes the ferredoxin-dependent oxidative
CC       decarboxylation of arylpyruvates.
CC   -!- CATALYTIC ACTIVITY: (Indol-3-yl)pyruvate + CoA + 2 oxidized
CC       ferredoxin = S-2-(indol-3-yl)acetyl-CoA + CO(2) + 2 reduced
CC       ferredoxin + H(+).
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       pH dependence:
CC         Optimum pH is 10.0;
CC       Temperature dependence:
CC         Optimum temperature is 80 degrees Celsius;
CC   -!- SUBUNIT: Heterodimer of the iorA and iorB subunits.
