Pyroglutamate Formation Influences Solubility and Amyloidogenicity of Amyloid Peptides
Abstract
N-Terminally truncated and pyroglutamate (pGlu) modified amyloid beta (Abeta) peptides are major constituents of amyloid deposits in sporadic and inherited Alzheimer's disease (AD). Formation of pGlu at the N-terminus confers resistance against cleavage by most aminopeptidases, increases toxicity of the peptides, and may seed Abeta aggregate formation. Similarly, the deposited amyloid peptides ABri and ADan, which cause a very similar histopathology in familial British dementia (FBD) and familial Danish dementia (FDD), are N-terminally blocked by pGlu. Triggered by the coincidence of pGlu-modified amyloid peptides and similar pathology in AD, FBD, and FDD, we investigated the impact of N-terminal pGlu on biochemical and biophysical properties of Abeta, ABri, and ADan. N-Terminal pGlu increases the hydrophobicity and changes the pH-dependent solubility profile, rendering the pGlu-modified peptides less soluble in the basic pH range. The pGlu residue increases the aggregation propensity of all amyloid peptides as evidenced by ThT fluorescence assays and dynamic light scattering. The far-UV CD spectroscopic analysis points toward an enhanced beta-sheet structure of the pGlu-Abeta. Importantly, changes in fibril morphology are clearly caused by the N-terminal pGlu, resulting in the formation of short fibers, which are frequently arranged in bundles. The effect of pGlu on the morphology is virtually indistinguishable between ABri, ADan, and Abeta. The data provide evidence for a comparable influence of the pGlu modification on the aggregation process of structurally different amyloid peptides, thus likely contributing to the molecularly distinct neurodegenerative diseases AD, FBD, and FDD. The main driving force for the aggregation is apparently an increase in the hydrophobicity and thus an accelerated seed formation.

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.
