Amyloid beta - Wikipedia
Early NMR-derived models of a 26-aminoacid polypeptide from amyloid beta (Aβ 10–35) show a collapsed coil structure devoid of significant secondary structure content. [56] However, the most recent (2012) NMR structure of (Aβ 1-40) has significant secondary and tertiary structure. [1]
Amyloid beta: structure, biology and structure-based …
In this paper, we review the structures, biological functions, and neurotoxicity role of Aβ. We also discuss the potential receptors that interact with Aβ and mediate Aβ intake, clearance, and metabolism. Additionally, we summarize the therapeutic developments and recent advances of different strategies for treating Alzheimer's disease.
RCSB PDB - 1BA4: THE SOLUTION STRUCTURE OF AMYLOID BETA-PEPTIDE (1-40 ...
1998年4月7日 · The three-dimensional solution structure of the 40 residue amyloid beta-peptide, Abeta(1-40), has been determined using NMR spectroscopy at pH 5.1, in aqueous sodium dodecyl sulfate (SDS) micelles. In this environment, which simulates to some extent a water-membrane medium, the peptide is unstructured between residues 1 and 14 which are mainly ...
Paired β-sheet structure of an Aβ(1-40) amyloid fibril ... - PNAS
2008年5月27日 · Here, we present a three-dimensional structure of a mature amyloid fibril formed by Aβ (1-40) peptide, determined by electron cryomicroscopy at ≈8-Å resolution. The fibril consists of two protofilaments, each containing ≈5-nm-long regions of β-sheet structure.
Complete aggregation pathway of amyloid β (1-40) and (1-42
To test this hypothesis, we deposited Aβ-40 and Aβ-42 peptides aggregated in PBS buffer aqueous solution (pH 7.4) onto a single-layer graphene surface (atomic structure and thickness verified through scanning tunneling microscopy; fig. S1) during different stages of aggregation ranging from 0.5 to 150 hours and monitored the morphological change...
RCSB PDB - 2LFM: A partially folded structure of amyloid-beta(1 40…
2011年7月6日 · While previous studies commonly show the Aβ(1-40) is largely unstructured in solution, we show that Aβ(1-40) can adopt a compact, partially folded structure. In this structure (PDB ID: 2LFM), the central hydrophobic region of the peptide forms a 3(10) helix from H13 to D23 and the N- and C-termini collapse against the helix due to the ...
Structures of beta-amyloid peptide 1-40, 1-42, and 1-55-the 672 …
2009年12月16日 · We report the structures of amyloid beta peptide (Abeta(1-40) and Abeta(1-42)) as well as the 672-726 fragment of APP (referred to as Abeta(1-55)) in a membrane environment determined by replica-exchange molecular dynamics simulation. Abeta(1-40) is found to have two helical domains A (13-22) and B(30-35) and a type I beta-turn at 23-27.
