Plastics are everywhere in our modern way of living, and their production keeps increasing
every year, causing major environmental concerns. Nowadays, the end-of-life management …

This volume of" Water-A Comprehensive Treatise" is devoted to aqueous solutions of
macromolecules and aqueous systems of small molecules which exhibit reversible …

A method of comparing the conformations of different, but structurally related proteins is
described. Local variations, such as the systematic translation of a helix, or the position of …

The solvent-accessible surface area (A s) of 46 monomeric proteins is calculated using
atomic co-ordinates from high-resolution and well-refined crystal structures. The A s of these …

Publisher Summary In the proper environment, a polypeptide chain can fold spontaneously
to the three-dimensional structure of a native protein, and despite the possible presence of …

A model is proposed to account for theobser-vation that the denaturation of small proteins
apparently occurs in two kinetic phases. It is suggested that only one of these phases—the …

The topological connectivities of β-pleated sheets in the known protein structures are
systematically surveyed for regularly occurring features. The many empirical restrictions …

The native structures of eight proteins are analyzed for the presence of chain reversals. Of
the 135 bends found, 129 belong to a set of ten types. Conformational energy calculations …

The X-ray atomic co-ordinates from 29 proteins of known sequence and structure were
utilized to elucidate 459 β-turns in regions of chain reversals. Tetrapeptides whose αC i αC …

A systematic classification of β-hairpin structures which takes into account the polypeptide
chain length and hydrogen bonding between the two antiparallel β-strands is described. We …
