== Function ==
[https://www.uniprot.org/uniprot/GCN4_YEAST GCN4_YEAST] Is a transcription factor that is responsible for the activation of more than 30 genes required for amino acid or for purine biosynthesis in response to amino acid or purine starvation. Binds and recognize the DNA sequence: 5'-TGA[CG]TCA-3'.

== Publication Abstract from PubMed ==
We report the complete structure determination of a 34 residue synthetic peptide with the amino acid sequence of the dimerization domain (leucine zipper) of GCN4. A high resolution structure in solution was obtained by 1H-NMR studies and distance geometry calculations followed by restrained energy minimization. A set of 20 final structures was obtained with an average root mean square deviation of 1.3 A for the backbone atoms (excluding the first and the last two residues). The structure contains an uninterrupted helix. A comparison with a structure previously determined for a larger peptide containing both the DNA-binding region (basic region) and the leucine-zipper motif shows the structural independence of the leucine-zipper domain from the contiguous DNA binding region.
