Macromolecular interaction is essential, necessary and unavoidable in a living organism. Specific interactions among macromolecules are required for molecular machinery assembly and for progression and regulation of metabolic reactions. To fully understand a biological process, it is essential to determine the atomic structures of and interactions among components of a macromolecular complex and to decipher how these structures and interactions change during a reaction or signaling cycle. Some macromolecular complexes are naturally stable, for example tetrameric hemoglobin, nucleosome, and ribosome. But most macromolecular complexes are formed only transiently, e.g. an enzyme and substrate complex, a growth factor and its receptor interaction, or transcription factors assembled on a promoter. To determine structures of macromolecular complexes, whether stable or transient, has become a common practice of structural biologists in the 21st century.
