Information About

Protein Complex




A Protein Complex is a group of two or more associated Protein s. Protein complexes are a form of Quaternary Structure . Understanding the functional Interaction s of proteins is an important research focus in Biochemistry , often referred to as Proteomics .

Similarly to Phosphorylation , complex formation often serves to activate or inhibit one or more of the associated proteins.

Many protein complexes are established, particularly in the model organism Saccharomyces Cerevisiae , a yeast. The discovery of protein complexes is now performed genome wide; the elucidation of most protein complexes of the yeast is undergoing.

The Molecular Structure of protein complexes can be determined by experimental techniques such as X-ray Crystallography or Nuclear Magnetic Resonance . Increasingly the theoretical option of Protein-protein Docking is also becoming available.
