Impact of nucleic acid self-alignment in a strong magnetic field on the interpretation of indirect spinā??spin interactions
Abstract
Heteronuclear and homonuclear direct (D) and indirect (J) spinā??spin interactions are important sources of structural information about nucleic acids (NAs). The Hamiltonians for the D and J interactions have the same functional form; thus, the experimentally measured apparent spinā??spin coupling constant corresponds to a sum of J and D. In biomolecular NMR studies, it is commonly presumed that the dipolar contributions...

Protein-DNA and protein-RNA complexes play key functional roles in every living organism. Therefore, the elucidation of their structure and dynamics is an important goal of structural and molecular biology. Nuclear magnetic resonance (NMR) studies of protein and nucleic acid complexes have common features with studies of protein-protein complexes: the...

alignment in a magnetic field
hi all,
I have a general question about alignment in a magnetic field.
For me, alignment in alignment media is easier to grasp because of interactions that I am familiar with as a chemist.
But, whats the principle behind molecules that align in a magnetic field?
There are a lot of examples like cyanometmyoglobin (from the Prestegard paper) where paramagnetic susceptibility plays a role. Thats understandable from my side.
But what about for instance short DNA dimers (helices), collagen gels or bacteriophages?
I could not really find a nice (clear to me) explanation, why these...
