Towards this goal, Compugen developed a sequence-based computational method for the prediction of intra-molecular interacting alpha helices.
The researchers found that the chains folded into spiral structures resembling alpha helices in proteins, suggesting that hydrogen bonds are not central to the folding of alpha helices.
Previous work had shown that combinations of just three amino acids are sufficient to form bundles of spiral-shaped structures called alpha helices.
