description: This entry represents a beta propeller domain composed of five blades. It is often found
  in large extracellular proteins in one or more copies. It is uncertain whether this domain might have
  an enzymatic function or a ligand binding function. Structurally this domain appears to have a sixfold
  symmetry, but one of the blades takes up the space of normal repeats. This unusual blade is composed
  of three strands of the first repeat and a final C-terminal strand from the last repeat.
