Resonance assignments and secondary structure analysis of E. coli thioredoxin by magic angle spinning solid-state NMR spectroscopy
Article Abstract:
C and N chemical shift assignments and secondary structure analysis for 108-amino acid residue E. coli thioredoxin is presented. Backbone dihedral angles and secondary structure are derived from the statistical analysis of the secondary chemical shifts, and are in good agreement with solution values for the intact full-length thioredoxin, with exception of small number of residues located at the termini of the individual secondary structure elements.

Inclusion complexes of PBN-type nitrone spin traps and their superoxide spin adducts with cyclodextrin derivatives: Parallel determination of the association constants by NMR triations and 2D-EPR simulations
Article Abstract:
(super 1)H NMR and electron paramagnetic resonance (EPR) titrations are used to determine the association constants of the complexes of alpha-penyl-N-tert-butylnitrone (PBN) analogues and their superoxide spin adducts, with methylated beta-cyclodextrin is presented. A cooperative system concerning the complexation of the nitroxide spin adduct with a cyclodextrin is evidenced by EPR titrations.

NMR investigations of the beta-cyclodextrin inclusion of (alpha-phenyl-N-tert-butylnitrone) analogues
Article Abstract:
The NMR studies of the inclusion complexes formed between beta-CD and different types of alpha-phenyl-N-tert-butylnitrone (PBN) derivatives are presented. The NMR technique allows the characterization of the inclusion process in terms of stoichiometry, association constant and geometry of the complexes.
