• PubMed Abstract: 
  

  We have refined the solution structure of cadmium-bound GAL4 and present its 15N and 1H NMR assignments. The root-mean-square (rms) deviation to the average structure was 0.4 +/- 0.05 A for backbone atoms, and 0.9 +/- 0.1 A for all heavy atoms. The three-bond heteronuclear 3J(113Cd,1H) coupling constants were found to disobey a Karplus-type relationship, which was attributable to the unusual constraints imposed by the bimetal-thiolate cluster in GAL4. We conclude that the structural parameters that correlate to 3J(113Cd,1H) are complex.
