They interpolate between ground states that are the secondary structures like  alpha-helices and beta-strands.  Entire proteins can then be folded simply by assembling  the solitons together, one after another. We present a simple theoretical model  that realizes our proposal and apply it to a number of biologically active proteins including 1VII, 2RB8, 3EBX (Protein Data Bank codes). In  all the examples that we have considered we are able to construct  solitons  that reproduce secondary structural motifs su","authors_text":"Antti J. Niemi, M.N.
