The binding sites of Zinc atom in the structure of Crystal Structure of Bchu Complexed With S-Adenosyl-L-Homocysteine and Zn-Bacteriopheophorbide D (pdb code 1x1d). This binding sites where shown with 5.0 Angstroms radius around Zinc atom. The 1x1d structure was solved by H.YAMAGUCHI, K.WADA, K.FUKUYAMA, with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
