Two main interfaces play an essential role in complex formation, the first interface between subunit A and B, and he second interface between A and F. The entrance to the internal cavity is blocked by three phenylalanine residues (Phe4), one for each of three monomers that compose half of the hexamer 730907 3.1.1.41 octamer 8 * 35000, strain SHS 0133, SDS-PAGE -, 170673, 170677 3.1.1.41 tetramer strain ATCC6633 -, 170673
