The 5 - membered ring of proline prevents rotation about alpha C - N bond and proline introduces a destabilizing kink in the alpha helix. In addition proline residue linked by an amide bond doesn't have a hydrogen atom to form hydrogen bonds with other residues. Therefore, Proline is also Known as Helix breaker. |
