Our results are consistent with a model whereby fast-folding proteins utilize a diffusion-collision mechanism, with the preorganization of one or more elements of secondary structure in the ...

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...

Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...
