Anisotropy of the molecular magnetic susceptibility gives rise to a small, degree of alignment. The resulting residual dipolar couplings, which can, now be measured with the advent of higher magnetic fields in NMR, contain, information on the orientation of the internuclear vectors relative to the, molecular magnetic susceptibility tensor, thereby providing information on, long range order that is not accessible by any of the solution NMR, parameters currently used in structure determination. Thus, the dipolar, couplings constitute unique and powerful restraints in determining the, structures of magnetically oriented macromolecules in solution. The method, is demonstrated on a complex of the DNA-binding domain of the, transcription factor GATA-1 with a 16 base pair oligodeoxyribonucleotide.

[https://www.uniprot.org/uniprot/GATA1_CHICK GATA1_CHICK] Transcriptional activator which probably serves as a general switch factor for erythroid development. It binds to DNA sites with the consensus sequence [AT]GATA[AG] within regulatory regions of globin genes and of other genes expressed in erythroid cells.

Thus, the dipolar couplings constitute unique and powerful restraints in determining the structures of magnetically oriented macromolecules in solution. The method is demonstrated on a complex of the DNA-binding domain of the transcription factor GATA-1 with a 16 base pair oligodeoxyribonucleotide.
