1YSA
1YSA is the PDB of GCN4 leucine zipper. The zipper is coil of alpha helices which interact through ion pairs and hydrogen bonding. The leucines make side-to-side interactions in every other layer of the dimer structure that is formed with the DNA (5).
Function of 1YSA
1YSA is a transcription factor that activates over 30 genes necessary for amino acid or biosynthesis. 1YSA binds to the DNA sequence: 5'-TGA[CG]TCA-3' (1).
Structure, Interactions, and Location
1YSA is a four chain, transcription factor. There are both polar and regions within 1YSA. It interacts with DNA and binds DNA as a dimer. 1YSA interacts in several locations within the DNA. Additionally, 1YSA interacts with the protein Gcn4. Within DNA, 1YSA binds to DNA (5'-3 D(*tp*tp*cp*cp*tp*ap*tp*gp*ap*cp*tp*cp*ap*tp*cp*cp*a4 P*gp*tp*t)-3') and DNA (5'-9 D(*ap*ap*ap*cp*tp*gp*gp*ap*tp*gp*ap*gp*tp*cp*ap*tp*a10 P*gp*gp*a)-3') (2). The location of 1YSA within a cell is in nucleus P03069 (3).
Origin
1YSA originates from the organism Saccharomyces cerevisiae, or commonly known as baker's yeast (4).
