A fold of a finite string S over a given alphabet is an embedding of S in some fixed infinite grid, such as the square or cubic mesh. The score of a fold is the number of pairs of matching string symbols which are embedded at adjacent grid vertices. Folds of strings in two-and threedimensional meshe

✦ Synopsis
It is believed that the native folded three-dimensional conformation of a protein is its lowest free energy state, or one of its lowest. It is shown here that both a two-and three-dimensional mathematical model describing the folding process as a free energy minimization problem is NPhard. This means that the problem belongs to a large set of computational problems, assumed to be very hard ("conditionally intractable"). Some of the possible ramifications of this result are speculated upon.

The most surprising feature of proteins, which distinguishes them from all other types of large polymeric molecules and provides them with a broad range of special properties, is their unique structural order. The position of each atom in these macromolecules is unique relative to its neighboring at
Protein physics is grounded on three fundamental experimental facts: protein, this long heteropolymer, has a well defined compact three-dimensional structure; this structure can spontaneously arise from the unfolded protein chain in appropriate environment; and this structure is separated from the u
## Abstract The first stage of protein self‐organization—the formation of a fluctuating secondary structure in the unfolded protein chain—is considered. The stereochemical theory is presented enabling one to calculate helix‐coil and β‐structure‐coil equilibrium constants. It is shown that the most
