Nitrogen 141-142 beta-secretase 2 Homo sapiens 4-9 3328221-11 1987 Detailed studies of Cu(II) and Ni(II) binding to albumin suggests that both metals have the same specific binding site at the NH2-terminal tripeptide sequence (Asp1-Ala2-His3...) involving the Asp alpha-NH2, His3 N (1) imidazole, two deprotonated peptide nitrogens (Ala2NH and His3NH), and Asp1 COO- group.
