description: This entry represents a domain from a family of uncharacterised proteins in the archaeal
  phylum Thermoproteota. The proteins are predominantly found in the order Sulfolobales, which includes
  genera such as Acidianus, Metallosphaera, and Sulfolobus. The domain is approximately 110 amino acids
  in length. The reviewed protein SSO0428 from Saccharolobus solfataricus is a representative member of
  this family. Proteins in this family are predicted to form a single long alpha helix. Structure prediction
  suggests that this protein does not form a homomeric coiled-coil complex. Based on genomic context this
  protein may be an accessory subunit of the V-type ATP synthase complex.
