Pseudosymmetry in the structure of myohemerythrin.

The three-dimensional structure of the protein myohemerythrin from retractor muscles of the sipunculan worn Themiste zostericola has been explored for the existance of approximately symmetry operators that locally interrelate portions of the molecule. First, the electron denisty distribution at 5.5 A resolution was examined. A local 2-fold axis that transposes the C-D helix pair into the A-B he...

Using Pseudosymmetry to Reduce Search Effort

Symmetry breaking exploits a relationship between solutions: that they occur in equivalence classes. Constraints may be added to exclude all symmetrically equivalent solutions but one, greatly reducing the search space. Using two problems we show that a weaker relationship can also be exploited: that the existence of one solution implies the existence of another but not necessarily vice versa. ...

Developments in AZtec: New Solutions for EBSD

Electron backscatter diffraction EBSD is a powerful technique applicable to a range of microstructural analyses, including texture, grain size, boundary characterization, phase distribution and inter-phase orientation relationships. The technique is suited to solving an increasing range of analytical problems on the um to mm scale. However, best results are only obtained with a good understandi...
