Additional NMR Experimental Information
DetailsThis structure was determined using standard two-dimensional 1H NMR techniques. This set of structures is the calculation of the initial fold of the domain without using restraints for zinc coordination. A second set of structures has been deposited that is a refinement of this fold using zinc coordination restraints based on EXAFS data for this domain.
