BIOINFORMATICS Reconsidering Complete Search Algorithms for Protein Backbone NMR Assignment
"... Motivation: Nuclear magnetic resonance (NMR) spectroscopy is widely used to determine and analyze protein structures. An essential step in NMR studies is determining the backbone resonance assignment, which maps individual atoms to experimentally measured resonance frequencies. Performing assignment ..."

The three-dimensional structure of phoratoxin in solution: combined use of nuclear magnetic resonance, distance geometry, and restrained molecular dynamics, Biochemistry 26
, 1987
"... ABSTRACT: The solution conformation of phoratoxin, a 46-residue plant protein, has been investigated by 'H nuclear magnetic resonance ( N M R) spectroscopy. The spectrum is assigned in a sequential manner by a combination of two-dimensional N M R techniques to demonstrate through-bond and thro ..."

Robust iterative fitting of multilinear models
- IEEE Transactions on Signal Processing
, 2005
"... Abstract—Parallel factor (PARAFAC) analysis is an extension of low-rank matrix decomposition to higher way arrays, also referred to as tensors. It decomposes a given array in a sum of multilinear terms, analogous to the familiar bilinear vector outer products that appear in matrix decomposition. PAR ..."

. PARAFAC analysis generalizes and unifies common array processing models, like joint diagonalization and ESPRIT; it has found numerous applications from blind multiuser detection and multidimensional harmonic retrieval, to clustering and nuclear magnetic resonance. The prevailing fitting algorithm in all
THE ANALYSIS OF COUPLING NETWORKS IN A COMPLEX OLIGOSACCHARIDE MIXTURE DERIVED FROM THE Fc REGION OF RABBIT IMMUNOGLOBULIN G USING 1 H- i H CORRELATED NMR SPECTROSCOPY COMBINED WITH DOUBLE QUANTUM NMR SPECTROSCOPY
, 1983
"... In glycoproteins, even for those containing a single glycosylation site, diversity is manifest in the occurrence of a family of structurally-related yet distinct oligosaccharides. To date this 'microheterogeneity ' is universal in mammalian glycoproteins. A method is described, using IH-IH ..."

-IH correlated and double quantum nuclear magnetic resonance NMR spectroscopy, for the assignment of proton resonances within a mixture of complex-type oligosaccharides derived from the Fc region of rabbit immunoglobulin G. The ability to assign resonances in heterogeneous populations will be of importance
PROTEINS: Structure, Function, and Genetics 32:26–42 (1998) AmbiPack: A Systematic Algorithm for Packing of Macromolecular Structures With Ambiguous Distance Constraints
"... ABSTRACT The determination of structures of multimers presents interesting new challenges. The structure(s) of the individual monomers must be found and the transformations to produce the packing interfaces must be described. A substantial difficulty results from ambiguities in assigning intermolecu ..."

High Resolution 3D Exchange NMR Spectroscopy and the Mapping of Connectivities between Half-integer Quadrupolar Nuclei
, 2002
"... The nuclear magnetic resonance (NMR) of spin S> 1/2 nuclei is usually dominated by their quadrupolar nature.1 Due to the anisotropy of this interaction, solid-state spectra of half-integer quadrupole nuclei have generally been restricted to the observation of central-1/2 T +1/2 transitions. Centr ..."
