description: This entry represents a small bacterial protein of unknown function. Its predicted structure
  shows a 6 stranded beta sheet with a C-terminal helix packed on one side. In a few proteins this domain
  is associated with [pfam:PF15595] a presumed immunity protein, which could suggest this domain may have
  a toxin function or be involved in a toxin/antitoxin system or in phage defence.
