Evaluating scenes representing the same structure
This sandbox compiles several student-generated scenes that illustrate properties of the Gal4 repressor.
Dimer
The protein binds as a to a symmetrical 17-base-pair sequence.
Domains
There is a compact (residues 8-40), an (41-49), and an (50-64).
Metal binding
A small, Zn(2+)-containing domain recognizes a conserved CCG triplet at each end of the site through direct contacts with the major groove. The metal binding domain contains that coordinate to the metal as shown as cadmium.
DNA/protein interaction
with all of the base pairs within 5 angstroms of the protein highlighted illustrates that the protein interacts with both strands of the UAS.
