Details | The biological assembly is an octamer constructed from chain A. The octamer has 42 symmetry and is entirely generated by crystallographic symmetry operations in the I422 tetragonal space group. His 49 from 2 different monomers along with 2 acetate ligands coordinate a zinc atom at the dimer interface. |
