Quantitative conformational analysis of the core region of N-glycans using residual dipolar couplings, aqueous molecular dynamics, and steric alignment.
A method is described for quantitatively investigating the dynamic conformation of small oligosaccharides containing an alpha(1 --> 6) linkage. It was applied to the oligosaccharide Man-alpha(1 --> 3) [Man-alpha(1 --> 6)] Man-alpha-O-Me, which is a core region frequently observed in N-linked glycans. The approach tests an aqueous molecular dynamics simulation, capable of predicting microscopic ...
متن کاملNew opportunities for tensor-free calculations of residual dipolar couplings for the study of protein dynamics.
Residual dipolar couplings (RDCs) can provide exquisitely detailed information about the structure and dynamics of proteins. It is challenging, however, to extract such information from RDC measurements in conformationally heterogeneous states of proteins because of the complex relationship between RDCs and protein structures. To obtain new insights into this problem, we discuss methods of calc...
متن کاملSimultaneous definition of high resolution protein structure and backbone conformational dynamics using NMR residual dipolar couplings.
Despite the importance of molecular dynamics for biological activity, most approaches to protein structure determination, whether based on crystallographic or solution studies, propose three-dimensional atomic representations of a single configuration that take no account of conformational fluctuation. Non-averaged anisotropic NMR interactions, such as residual dipolar couplings, that become me...
متن کاملDipolar couplings as a probe of molecular dynamics and structure in solution.
The introduction of residual dipolar coupling methodology has increased the scope of structural biological problems that can be addressed by NMR spectroscopy. Conformational changes, the relative orientation of domains, and intermolecular complexes can now be characterized accurately and rapidly using NMR. The development of residual dipolar coupling methodology for the rapid recognition of hom...
متن کاملLine narrowing in spectra of proteins dissolved in a dilute liquid crystalline phase by band-selective adiabatic decoupling: application to 1HN-15N residual dipolar coupling measurements.
Residual heteronuclear dipolar couplings obtained from partially oriented protein samples can provide unique NMR constraints for protein structure determination. However, partial orientation of protein samples also causes severe 1H line broadening resulting from residual 1H-1H dipolar couplings. In this communication we show that band-selective 1H homonuclear decoupling during data acquisition ...
