About this StructureAbout this Structure
GCN4 (PDB 2zta by itself, 1ysa bound to DNA) is a eukaryotic transcription factor first isolated from yeast. It is composed of two identical 52 residue alpha helix chains that grouped together to form a dimer. The dimer binds through interlocking leucine amino acids in the C terminal ends, while pinching in on the major groove of DNA in the N terminal end. The X-ray structure of the 33-residue polypeptide corresponding to the leucine zipper of GCN4 was determined by Peter Kim and Thomas Alber. [1]
