詳細 | The crystallographic asymmetry unit of insulin consists of two monomers each consisting two heterochains. The entry presents coordinates for monomer 1 (chain indicators A and B)and monomer 2 (chain indicators C and D). There are two zinc ions per insulin hexamer located on the three-fold axis. The conformations of two monomers are different the result of B changed in conformation of the first residues of the B-chain. The biological assembly is a hexamer generated from the dimer in the asymmetric unit by the operations: -y,x-y,z and -x+y,-x,z |
