'''GAL4 (CD), NMR, 24 STRUCTURES'''<br />


==Overview==
==GAL4 (CD), NMR, 24 STRUCTURES==
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.

== Function ==
[https://www.uniprot.org/uniprot/GAL4_YEAST GAL4_YEAST] This protein is a positive regulator for the gene expression of the galactose-induced genes such as GAL1, GAL2, GAL7, GAL10, and MEL1 which code for the enzymes used to convert galactose to glucose. It recognizes a 17 base pair sequence in (5'-CGGRNNRCYNYNCNCCG-3') the upstream activating sequence (UAS-G) of these genes.

== Publication Abstract from PubMed ==
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.
