Segmental motion in pseudomonic acid A: a carbon-13 spin-lattice relaxation time study at two field strengths.
نویسندگان
چکیده
The mobility of pseudomonic acid A in dimethyl sulfoxide-d6 solution has been determined from 13C spin-lattice relaxation time measurements at two field strengths. The central tetrahydropyran ring reorientates isotropically with a rotational correlation time of approximately 280 picoseconds/ radian . Both side-chains exhibit marked segmental motion with correlation times decreasing to only approximately 50 picoseconds/ radian at the end of the nonanoic acid side-chain.

Rotational motions in myoglobin assessed by carbon 13 relaxation measurements at two magnetic field strengths.
Proton-decoupled Fourier transform nuclear magnetic resonance spectroscopy of natural abundance 13C was used to obtain spectra of cyanoferrimyoglobin of sperm whale (Physeter catadon) at 14.1 and 23.5 kG. Comparison of the spin lattice relaxation times at these two field strengths allowed the unambiguous assignment of a rotational correlation time of 22 plus or minus 5 ns for the alpha carbon r...
متن کاملAn NMR study of 13C-enriched galactose attached to the single carbohydrate chain of hen ovalbumin. Motions of the carbohydrates of glycoproteins.
In order to facilitate the study of motions of the carbohydrate moiety of glycoproteins, a method of enzymatically attaching uniformly 13C-enriched galactopyranose ([U-13C]galactose) onto the nonreducing end of the carbohydrate chain has been developed. Specifically, [U-13C]glucose (20% 13C) was converted through a sequence of four enzymatic steps to [U-13C]UDP-galactose which was then attached...
متن کاملRestricted Internal Segmental Rotational Diffusion Model with Segment-Segment Interactions. Application to “C NMR
The restricted rotational-diffusion model developed by Wittebort and S&o (J. Chem. Phys. 69, 1722 (1978)) and London and Avitabile (J. Am. Chem. Sot. 100,7159 (1978)) is extended to include in a mean field sense, dynamic interactions between the diffusing motional unit, and an environment that may have Fourier components on the same time scale as the reorienting unit. Furthermore in contrast to...
متن کاملNuclear magnetic resonance spectroscopy. Carbon-13 spin-lattice relaxation time measurements of amino acids.
The (13)C spin-lattice relaxation times, T(1)'s, of several amino acids have been measured as a function of pD and concentration. A strong dependence of the carboxyl carbon T(1) was observed for both pD and concentration and is believed to be due to intermolecular associations. For the carboxyl carbon, spin rotation is proposed as the predominant relaxation mechanism, whereas the other carbons ...
متن کاملTemperature dependence of the Spin-Lattice Relaxation Time
The spin-lattice relaxation time, TX, of the 2 3 N a N M R line in N a N 0 2 is measured between 25 K and 160 K at two magnetic field strengths, 1.1 T and 6.9 T. The temperature dependence of TX for the center line, observed on a polycrystalline sample prepared by precipitation from aqueous solution, is given by a monotonous curve. Tx increases gradually as the temperature decreases. On the oth...
