WebThe upgraded force field for zinc (II)-bound residues has been tested performing molecular dynamics simulations with an explicit solvent and comparing the structural information with experimental data for five different proteins binding zinc (II) with GLU, ASP, HIS, and CYS. WebThe zinc finger is an independently folded domain with a compact globular structure in which the zinc atom is bound by two cysteine and two histidine ligands. The polypeptide backbone fold consists of a well-defined helix, starting as alpha and ending as 3 (10) helix, packed against two beta strands that are arranged in a hairpin structure.
