Structure of crystalline actin sheets

Nature, 1980
Although actin is one of the most abundant proteins found in nature, little detailed information about its molecular structure is available beyond the amino acid sequence. Electron microscopy of negatively stained filaments combined with three-dimensional image reconstruction techniques have revealed the overall size and shape of the actin monomer at ...

Crystalline Structures of Alginic Acids

Nature, 1970
WE have recently obtained X-ray diffraction photographs from orientated samples of alginic acid preparations in which the ratio of mannuronic acid to guluronic acid was known. The purified unorientated material was supplied by Dr A. Haug, and our results form the basis for structure determinations of polymannuronic acid and polyguluronic acid ...

Structure of crystalline methyl-chymotrypsin

Journal of Molecular Biology, 1972
Alpha-chymotrypsin, methylated specifically at the Nδ2-position of His-57, crystallizes isomorphously with the native enzyme. This finding enabled us to determine the structure of methyl-chymotrypsin utilizing the phase information of tosyl-chymotrypsin.

Macromolecular structure and liquid crystallinity

Faraday Discussions of the Chemical Society, 1985
The relationship between low-molar-mass or monomeric liquid crystals and polymeric liquid crystals is explored by examining the historical development of experimental and theoretical aspects of the latter materials. Polymeric liquid crystals are initially contrasted with conventional, non-mesogenic, flexible polymer chains (random coils), and then ...

Crystalline Plasticity and Structured Deformations

2004
The connection between the geometrical changes at small length scales in single crystals and their macroscopic response has been the subject of extensive experimental studies. In (Deseri and Owen (2000)), experimental evidence that points to a connection between hardening behavior of single crystals undergoing single slip and changes in the separation ...
