description: This is a family of uncharacterised proteins found in archaea and bacteria. These proteins
  are predicted to adopt similar structure to the members of SufE/NifU superfamily. They contain three
  invariant cysteine residues and a fourth semi-conserved residue either cysteine or histidine. These
  residues are likely to define a potential Zn-binding site similar to the binding site observed in SufU.
