Kinetic and structural characterization of amyloid‐β peptide hydrolysis by human angiotensin‐1‐converting enzyme

UNLABELLED Angiotensin-1-converting enzyme (ACE), a zinc metallopeptidase, consists of two homologous catalytic domains (N and C) with different substrate specificities. Here we report kinetic parameters of five different forms of human ACE with various amyloid beta (Aβ) substrates together with high resolution crystal structures of the N-domain in complex with Aβ fragments. For the physiologic...

Amyloid-β peptide promotes bacterial aging

The pathological hallmark of Alzheimer's disease is brain deposition of senile plaques composed predominantly of amyloid fibrils. These conformational structures, characteristic of many other human disorders, are formed mainly by the amyloid-β peptide Aβ42. This peptide, which is primarily disordered and soluble as an isolated monomer, can undergo an aggregation and fibrillation process that re...

Polymorphism of Oligomers of a Peptide from β-Amyloid

This contribution reports solution-phase structural studies of oligomers of a family of peptides derived from the β-amyloid peptide (Aβ). We had previously reported the X-ray crystallographic structures of the oligomers and oligomer assemblies formed in the solid state by a macrocyclic β-sheet peptide containing the Aβ(15-23) nonapeptide. In the current study, we set out to determine its assemb...

Metabolism of amyloid β peptide and pathogenesis of Alzheimer’s disease

The conversion of what has been interpreted as "normal brain aging" to Alzheimer's disease (AD) via transition states, i.e., preclinical AD and mild cognitive impairment, appears to be a continuous process caused primarily by aging-dependent accumulation of amyloid β peptide (Aβ) in the brain. This notion however gives us a hope that, by manipulating the Aβ levels in the brain, we may be able n...
