Partially-deuterated samples of HET-s(218â??289) fibrils: assignment and deuterium isotope effect
Partially-deuterated samples of HET-s(218â??289) fibrils: assignment and deuterium isotope effect
Abstract
Fast magic-angle spinning and partial sample deuteration allows direct detection of 1H in solid-state NMR, yielding significant gains in mass sensitivity. In order to further analyze the spectra, 1H detection requires assignment of the 1H resonances. In this work, resonance assignments of backbone HN and Hα are presented for HET-s(218â??289) fibrils, based on the existing assignment of Cα, Cβ, Câ??, and N resonances. The samples used are...

Amino acid recognition for automatic resonance assignment of intrinsically disordered proteins
Amino acid recognition for automatic resonance assignment of intrinsically disordered proteins
Abstract
Resonance assignment is a prerequisite for almost any NMR-based study of proteins. It can be very challenging in some cases, however, due to the nature of the protein under investigation. This is the case with intrinsically disordered proteins, for example, whose NMR spectra suffer from low chemical shifts dispersion and generally low resolution. For these systems, sequence specific assignment is highly time-consuming, so the prospect of using...

We describe a new efficient strategy for the sequential assignment of amide resonances of a conventional 15N-1H HSQC spectrum of intrinsically unfolded proteins, based on composite NOESY-TOCSY and TOCSY-NOESY mixing times. These composite mixing times lead to a...
