Alpha sheet (also known as alpha pleated sheet or polar pleated sheet) is an atypical secondary structure in proteins, first proposed by Linus Pauling and Robert Corey in 1951. The hydrogen bonding pattern in an alpha sheet is similar to that of a beta sheet, but the orientation of the carbonyl and amino groups in the peptide bond units is

When these two polypeptides meet, they fold into a functional four-helix bundle. The underrepresented residue types correlate with low beta sheet propensity

In the alpha helix the residues are pointed towards the outside while in the beta helix they are pointed towards the inside. The Alpha Helix, Beta Sheet, and Beta Turn. The existence of the alpha helix was predicted by Pauling and Cory from careful structural studies of amino acids and peptide bonds. This pre-diction came before identification of the alpha helix in X-ray diffraction patterns of proteins. Even though the data were all there, it was over-looked. structures [2], the transition between alpha helices and beta sheets ( - transition) is observed universally for a broad range of alpha-helix based protein filaments.
