description: This entry represents the N-terminal domain of the Pseudomonas bacteriophage E217 tail sheath
  protein gp31 and related proteins, including phage Pa193 gp32 and Shigella flexneri bacteriophage Sf14
  gp39. It folds into an alpha/beta structure that shares similarity with the members of the TssC1 N-terminal
  domain superfamily [[cite:PUB00163741],[cite:PUB00163742],[cite:PUB00153918]].
