Details | The biological assembly is a heterotetramer. There is a crystallographic two-fold axis through the center of the heterotetramer, passing through a small hydrophobic cavity between the two chain A molecules of the heterotetramer at approximate coordinates (47.61, 34.32, 13.52). The heterotetramer is held together by the two chain A molecules, with the two chain B molecules making few close contacts with each other. |
