Oligomeric arrangement of TL5A subunits around the fourfold crystallographic axis. Secondary structure elements involved in intermonomer packing are colored green (monomer A) and yellow (monomer D). In addition, some specific side chains are given with all nonhydrogen atoms. Notice in particular some planar arginine-aromatic side chain stacking similar to the ones frequently encountered in protein structures (31).
