A protein complex is a group of two or more associated proteins formed by protein-protein interaction that is stable over time. Protein complexes are a form of quaternary structure. Understanding the functional interactions of proteins is an important research focus in biochemistry and cell biology. A representation of the 3D structure of myoglobin, showing coloured alpha helices. ... Protein-protein interactions refer to the association of protein molecules and the study of these associations from the perspective of biochemistry, signal transduction and networks. ... In biochemistry, many proteins are actually assemblies of more than one protein (polypeptide) molecule, which in the context of the larger assemblage are known as protein subunits. ... Interaction is a kind of action that occurs as two or more objects have an effect upon one another. ... Biochemistry is the study of the chemical processes and transformations in living organisms. ... Cell biology (also called cellular biology or formerly cytology, from the Greek kytos, container) is an academic discipline that studies cells. ...
Similarly to phosphorylation, complex formation often serves to activate or inhibit one or more of the associated proteins. A phosphorylated serine residue Phosphorylation is the addition of a phosphate (PO4) group to a protein or a small molecule or the introduction of a phosphate group into an organic molecule. ...
Protein Forest: Rapid Seperation of ComplexProtein Mixtuers
Protein Forest has developed a technological breakthrough that enables the rapid fractionation of proteins by their isoelectric points.
The dPC™ product platform is used to enhance the sensitivity and performance of protein analysis techniques, such as mass spectrometry, chromatography and immunoblotting, by providing a rapid and reliable separation of complexprotein mixtures into fractions that are easier to analyze.
