REDOR-determined distances from heterospins to clusters of 13C labels.
نویسنده
چکیده
The use of rotational-echo double resonance NMR to measure distances from an observed tightly coupled cluster of 13C spins to a distant 15N, 31P, or 19F is practical if all homonuclear 13C-13C dipolar interactions are suppressed by multiple-pulse decoupling during heteronuclear dipolar evolution. This scheme is first calibrated by experiments performed on multiply labeled alanines and then applied in the measurement of 19F-13C distances in p-trifluoromethylphenyl [1,2-13C2]acetate.

Conformational analysis of the Saccharomyces cerevisiae tridecapeptide mating pheromone by 13C,15N rotational-echo double resonance nuclear magnetic resonance spectroscopy.
The solid-state conformation of [Nle12]alpha-factor, the Saccharomyces cerevisiae tridecapeptide mating pheromone (WHWLQLKPGQPNleY), was investigated by 13C,15N rotational-echo double resonance (REDOR) nuclear magnetic resonance spectroscopy (NMR). Previous high-resolution NMR studies of [Nle12]alpha-factor in solution revealed a transient Type II beta-turn spanning residues 7-10 of the peptide...
متن کاملFrozen-solution conformational analysis by REDOR spectroscopy.
Frozen-solution conformational analysis (FrSCA) can be performed on organic compounds using REDOR spectroscopy. REDOR measurements on frozen aqueous solutions of 13C-methyl beta-15N-aminoglucoside indicate a bimodal distribution of conformations in a 68:32 ratio, with 13C-15N distances of 4.31 and 3.55 A, respectively. The high resolution and straightforward sample preparation make FrSCA an att...
متن کاملMeasurements of carbon to amide-proton distances by C-H dipolar recoupling with 15N NMR detection.
A new magic-angle spinning NMR method for measuring internuclear distances between a 13C-labeled site and amide protons is described. The magnetization of the protons evolves under homonuclear decoupling and the recoupled 13C-1H dipolar interaction, which provides simple spin-pair REDOR curves if only one 13C-labeled site is present. The modulation of the amide proton HN is detected via short 1...
متن کاملApplication of REDOR subtraction for filtered MAS observation of labeled backbone carbons of membrane-bound fusion peptides.
Clean MAS observation of 13C-labeled carbons in membrane-bound HIV-1 and influenza fusion peptides was made by using a rotational-echo double-resonance spectroscopy (REDOR) filter of directly bonded 13C-15N pairs. The clean filtering achieved with the REDOR approach is superior to filtering done with sample difference spectroscopy. In one labeling approach, the peptide had labels at a single 13...
متن کاملProbing hydrogen bonds in the antibody-bound HIV-1 gp120 V3 loop by solid state NMR REDOR measurements.
We describe solid state NMR measurements on frozen solutions of the complex of the 24-residue HIV-1 gp120 V3 loop peptide RP135 with the Fab fragment of the anti-gp120 antibody 0.5beta, using rotational echo double resonance (REDOR). In order to probe possible hydrogen bonding between arginine side chains and glycine backbone carbonyls in the region of the conserved Gly-Pro-Gly-Arg (GPGR) motif...
