Alanine-2 Carbonyl is an Oxygen Ligand in Cu2+ Coordination of Alzheimer’s Disease Amyloid-β Peptide − Relevance to N-Terminally Truncated Forms
Abstract
Copper interactions with the beta-amyloid peptide (Abeta) are believed to play a role in Alzheimer's disease (AD), in particular due to production of reactive oxygen species and Cu(2+)-mediated oligomerization. To understand the role that copper might play in these processes, a detailed knowledge of the fundamental Cu(2+)/Abeta interactions is essential. To date, the identity of the oxygen ligand(s) involved in Cu(2+) coordination by Abeta has remained unclear. Here, we have used site-specific (13)C and (15)N labeling in conjunction with hyperfine sublevel correlation (HYSCORE) spectroscopy to unambiguously identify the carbonyl of Alanine-2 as an oxygen ligand in one of the pH-dependent Cu(2+) coordination modes of Abeta. Polarization of the carbonyl moiety by Cu(2+) could promote amide hydrolysis and cleavage of the peptide bond between Ala2 and Glu3, providing a chemical mechanism for the generation of truncated Abeta 3-40/42 species found in AD plaques.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
