This change is often a conformational one, causing the protein to change how it is structured (see Figure 2). Figure 2. Conformation changes caused by phosphorylation.
Phosphorylation introduces a charged and hydrophilic group in the side chain of amino acids, possibly changing a protein's structure by altering interactions with nearby amino acids. Some proteins such as p53 contain multiple phosphorylation sites, facilitating complex, multi-level regulation. Because of the … See more Protein phosphorylation is a reversible post-translational modification of proteins in which an amino acid residue is phosphorylated by a protein kinase by the addition of a covalently bound phosphate group. … See more Reversible phosphorylation of proteins is abundant in both prokaryotic and even more so in eukaryotic organisms. For instance, in bacteria 5-10% of all proteins are thought to be phosphorylated. By contrast, it is estimated that one third of all human proteins … See more While tyrosine phosphorylation is found in relatively low abundance, it is well studied due to the ease of purification of phosphotyrosine using antibodies.
