Protein attributes

Sequence length	1174 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin Potential.
Catalytic activity	Pyruvate + CoA + oxidized flavodoxin = acetyl-CoA + CO₂ + reduced flavodoxin.
Sequence similarities	Belongs to the NifJ family. Contains 2 4Fe-4S ferredoxin-type domains.
Sequence caution	The sequence U36928 differs from that shown. Reason: Frameshift at position 35.
