description: This domain is found in a group of small proteins mainly from Halobacteria. It contains highly
  conserved cysteine and histidine residues arranged in two CxxC and HxxC motifs that likely coordinate
  zinc. This domain is predicted to adopt a fold similar to the classical C2H2 and variant C2HC zinc fingers
  containing beta-hairpin and an alpha helix. In addition, it is predicted to contain an extra N-terminal
  strand that contributes to the formation of a three-stranded antiparallel beta-sheet. This domain also
  has a number of highly conserved negatively charged residues.
