Post-translational modifications (PTM) such as O-phosphorylation of tyrosine (Tyr) and serine (Ser) and 3-nitration of Tyr amino acid residues of proteinaceous molecules were successfully detected by electrochemistry with the amyloid-beta (1–16) peptide (Aβ16) as an example. The detection strategy was based on the effects of Tyr or Ser O-phosphorylation and Tyr 3-nitration on electrochemical activity...
The aggregation of amyloid‐β peptide (Aβ) is believed to play a crucial role in the Alzheimer's disease (AD) pathogenesis and is considered as a therapeutic target for treating AD. The Aβ electrooxidation via a Tyr‐10 residue, sensitive to a depletion of a pool of Aβ monomers and oligomers in the course of Aβ aggregation, may be employed for testing natural and synthetic organic compounds (including...
