WebSnippet: Glutamic acid in the Ramachandran plot. The structure of a protein can be described using torsion angles-φ and ψ-of its backbone that provides a simple view of the conformation of a protein. WebProteins with a bZIP domain are grouped into one super-family. They are distinct from other proteins that contain similar structural elements like the numerous proteins with only leucine zippers or the basic helix-loop-helix leucine zipper proteins in which basic region and leucine zipper are functionally equivalent to those of bZIP proteins but are separated by …
