The binding sites of Zinc atom in the structure of Schiff-Base Complex of Yeast 5-Aminolaevulinic Acid Dehydratase With Laevulinic Acid At 1.6 A Resolution (pdb code 1h7n). This binding sites where shown with 5.0 Angstroms radius around Zinc atom. The 1h7n structure was solved by P.T.ERSKINE, R.NEWBOLD, A.A.BRINDLEY, S.P.WOOD, P.M.SHOOLINGIN-JORDAN, M.J.WARREN, J.B.COOPER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
