Elemental quantitation of natural organic matter by CPMAS 13C NMR spectroscopy.
Cross-polarized magic-angle-spinning NMR (CPMAS-NMR) techniques are assumed to be only semi-quantitative in the assessment of carbon distribution in humic substances or natural organic matter, due to a number of interferences such as spinning side bands (SSB) in spectra, paramagnetic species in samples, and low or remote protonation of aromatic carbons. Fast rotor spin rates or direct polarizat...
متن کاملStructural studies of amphiphilic oligopeptides composed of alternating alanine and ionizable amino-acid residues using CD and 13C CPMAS NMR spectroscopy
We report a novel self-assembling system of amphiphilic oligopeptides composed of alternating hydrophobic and ionizable amino-acid residues. Three types of peptides, AD12, AE12 and AK12, were prepared as building blocks for this model system. These peptides formed helical conformations in low-concentration solutions, but these peptides adopted b-sheet structures and precipitated in highly conce...
متن کاملSome Applications of Ultrahigh Resolution 15N NMR Spectroscopy
Ultrahigh resolution l5N NMR spectra were measured for two nitroalkanes (MeNÜ2 la, fBuN02 lc), two isocyanates (;BuNCO 2c, Me^SiNCO 2d), four isothiocyanates (MeNCS 3a, EtNCS 3b, 'BuNCS 3c, M e3SiNCS 3d), one carbodiimide (Me3 SiNCNSiMe3 4d), one keteneimine [Me3 SiNCC(SiMe3 ) 2 5d], two sulphinyl imides ('BuNSO 6c, Me3 SiNSO 6d), and N-terf-butyl-pyrrole 7c, in order to determine coupling cons...
متن کاملCell-free synthesis of 15N-labeled proteins for NMR studies.
Modern cell-free in vitro protein synthesis systems present powerful tools for the synthesis of isotope-labeled proteins in high yields. The production of selectively 15 N-labeled proteins from 15 N-labeled amino acids is particularly economic and yields are often sufficient to analyze the proteins very quickly by two-dimensional NMR spectra recorded of the crude reaction mixture without concen...
متن کاملMeasuring protein reduction potentials using 15N HSQC NMR spectroscopy†
NMR spectroscopy was used to measure reduction potentials of four redox proteins by following multiple (15)N HSQC protein resonances across a titration series using mixtures of oxidised and reduced glutathione. Results for PDI a, PDI ab and DsbA agree with the literature and our result for ERp18 confirms this protein as an oxidoreductase of comparable or greater reducing strength than PDI a.
