Biomolecular complex

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Biomolecular complex, also called macromolecular complex or biomacromolecular complex, is any biological complex made of more than one molecule of protein, RNA, DNA, [1] lipids, carbohydrates. The interactions between these biomolecules are non-covalent. [2] Examples:

The biomacromolecular complexes are studied structurally by X-ray crystallography, NMR spectroscopy of proteins, cryo-electron microscopy and successive single particle analysis, and electron tomography. [3] The atomic structure models obtained by X-ray crystallography and biomolecular NMR spectroscopy can be docked into the much larger structures of biomolecular complexes obtained by lower resolution techniques like electron microscopy, electron tomography, and small-angle X-ray scattering.
