Comments [?]

case <FTTag:persulfide>
Function Required for formate dehydrogenase (FDH) activity. Acts as a sulfur carrier protein that transfers sulfur from IscS to the molybdenum cofactor prior to its insertion into FDH.
else
Function Required for formate dehydrogenase (FDH) activity.
end case
Subcellular location Cytoplasm.
Similarity Belongs to the FdhD family.
