Correlation time measurements using cross-correlation based NMR spin relaxation experiments suggest that the three zinc finger motifs are connected by flexible loops and not restricted with respect to one another. Residual dipolar couplings also indicate that the three domains are oriented independently. Therefore the positions of domains with respect to one another in the structures reported are not significant.
