Cu(II) coordination in Proteins

Coordination Features and Affinity of the Cu2+ site in the alpha-Synuclein Protein of Parkinson’s Disease Dudzik, C.G.; Walter, E.D. and Millhauser, G.L. Biochemistry ASAP Alpha-synuclein proteins, concentrated in neurons in the human body, are composed of mostly hydrophobic residues. The hydrophobicity of the protein results in frequent aggregation or ‘clumping together’ of multiple alpha-syn proteins … Continue reading
