description: 'The family of bacterial Anabaena sensory rhodopsin transducers are likely to bind sugars
  or related metabolites. The entire protein is comprised of a single globular domain with an eight-stranded
  beta-sandwich fold. There are a few characteristics which define this beta-sandwich fold as being distinct
  from other so-named folds, and these are: 1) a well conserved tryptophan, usually following a polar
  residue, present at the start of the first strand; this tryptophan appears to be central to a hydrophobic
  interaction required to hold the two beta-sheets of the sandwich together, and 2) a nearly absolutely
  conserved asparagine located at the end of the second beta-strand, that hydrogen bonds with the backbone
  carbonyls of the residues 2 and 4 positions downstream from it, thereby stabilising the characteristic
  tight turn between strands 2 and 3 of the structure.'
