   trimer, one subunit folds into (16,20) barrel

2. f.4.3.2: Maltoporin-like [56942] (2 proteins)
   trimer, one subunit folds into (18,22) barrel
   automatically mapped to Pfam PF02264

3. f.4.3.3: Ligand-gated protein channel [56948] (5 proteins)
   monomeric (22,24) barrel; ~150 N-terminal residues form a "plug" or "cork" subdomain
