crystallography

 [kris″tah-log´rah-fe]
the science dealing with the study of crystals.
x-ray crystallography the determination of the three-dimensional structure of molecules by means of diffraction patterns produced by x-rays of crystals of the molecules.

X-ray crystallography

a powerful technique for determining the structure of crystalline substances by measuring the diffraction patterns produced when a beam of X-rays is passed through the crystal. X-ray crystallography has provided information on the 3-D structure of PROTEINS, NUCLEIC ACIDS, DRUGS, HORMONES, VITAMINS and so on, from which atomic models can be built. Knowledge of the structure of such molecules has provided insight into how they function, and is useful in PROTEIN ENGINEERING.

The information resulting from the subsequent x-ray diffraction analysis can be used by researchers to help determine the three-dimensional structure of a macromolecule that, in turn, may reveal details about the molecule's function and behavior in the body.
To gain further insight into the structure and function of C8[gamma], a recombinant form of human C8[gamma] was crystalized and subjected to X-ray diffraction analysis. Results revealed a [beta]-barrel structure, typical of the lipocalin family, which contains a defined binding site for a small as yet unidentified ligand.
