The plot below is a hydrophobicity plot for the primary structure of a protein. The hydrophobicity of each amino acid is plotted from the N-terminus (aa1) to the C-terminus (aa2001). Amino acids that are more hydrophobic are towards the top, and those that are hydrophilic are towards the bottom. Given the potential locations on the […]
