Structural Biology

The Steps toward Elucidating the Structures of Biological Macromolecules by X-ray crystallography.

Structural Biology is a branch of molecular biology & biochemistry concerned with the the molecular structure of biological macromolecules like proteins and nucleic acids. It focuses on determining the structure of macromolecules to better understand their function and how to manipulate these macromolecules to develop therapeutics and broaden our understanding of biological phenomena.
