description: This family of proteins contains 8 conserved cysteines. It has in the past been annotated
  as being one of the complex of proteins of the flagellar Fli complex. However this was due to a mis-annotation
  of the original Salmonella LT2 Genbank entry of 'fliB'. With all its conserved cysteines it is possibly
  a domain that chelates iron or zinc ions.
