 Biological
Crystallography (BX, MX, PX) is a technique used to determine the
3-dimensional structures of biological molecules such as proteins,
viruses and nucleic acids (RNA and DNA) to a resolution higher than
~5 Angstrom. From the studies of this structural information, the
detailed mechanism of the biological functions carried out by those
macromolecules in living cells and organisms can be elucidated.
The x-rays deflected ("scattered") by a single crystal
of biological molecules concentrate into sharp intense spots (crystal
diffraction pattern), and the structure of the biological molecule
can be determined by analysis of the intensities and positions of
the diffraction spots. There are currently three biological crystallography
beamlines in operation, some general information are listed here,
and for more detailed information please visit the website of the
Biological Crystallography Facility at NSRRC.
