Secondary Structure
The is formed by hydrogen bonding interactions of the amino acids backbone. There are two beta-sheet regions in each monomer of the natural dimer. Five beta-sheets in each monomer are anti-parallel, and form a pseudo beta-barrel motif. Six beta-sheets in each monomer show parallel configuration. The angle of the hydrogen bonds relative to one another between beta-sheets gives insight as to which beta-sheets are parallel and which are anti-parallel. Parallel beta-sheets have "crooked" h-bonding. This makes them more unstable than the anti-parallel beta-sheets which have straight h-bonds between them.
