Molecular Insights into Cu/Zn Metal Response to the Amyloid β-Peptide (1–42)
Anurag Prakash Sunda* and Anuj Kumar Sharma*
Aβ1–40 peptide and Aβ1–42 peptide are the building units of beta-amyloid plaques present in Alzheimer’s disease (AD)-affected brain. Cu2+ metal ions are known to enhance the neurotoxicity of the Aβ1–42 peptide by catalyzing the formation of soluble neurotoxic oligomers. The competitive preference of both Cu2+ and Zn2+ simultaneously to interact with the Aβ-peptide is unknown.
