Significats de alpha helices en anglès

Approximately 40% of the BCCL2 secondary structure consisted of alpha helices.

The structure contains three alpha helices, as reported previously for theta; however, the folding topology of the two proteins is very different.

Periodicity in the pattern of tolerated vs. nontolerated mutations consistent with alpha helices or beta strands did not emerge convincingly from these data.

A classification model of a DNA-binding protein chain was created based on identification of alpha helices within the chain likely to bind to DNA.

H(N)-H(N) NOEs provided information on the assembly of the extended strands into a beta-sheet structure and confirmed the assignment of the alpha helices.

For each of the candidate structures, possible sites of DNA-binding are indicated by listing the residue ranges of alpha helices likely to interact with DNA.

IBV nsp9 forms a homodimer via interactions across a hydrophobic interface, which consists of two parallel alpha helices near the carboxy terminus of the protein.

Partial loss of alpha-helical content and dissociation of dimers occurred at 42°C, with the residual alpha helices remaining stable up to 80°C.

However, deletion of a C-terminal region of apoA-IV, which is devoid of predicted amphipathic alpha helices (amino acids 333-376) stimulated both of these activities dramatically.
