CC   -!- FUNCTION: Oxidoreductase required for the transfer of electrons from
CC       pyruvate to flavodoxin, which reduces nitrogenase.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=CoA + 2 H(+) + oxidized [flavodoxin] + pyruvate = acetyl-CoA +
CC         CO2 + reduced [flavodoxin]; Xref=Rhea:RHEA:44140, Rhea:RHEA-

CC   -!- SIMILARITY: Belongs to the pyruvate:ferredoxin/flavodoxin
CC       oxidoreductase family. {ECO:0000305}.
