Phоsphоrylаtiоn is а key post-trаnslational modification of proteins that plays a crucial role in regulating cellular processes. It involves the addition of a phosphate group, typically from adenosine triphosphate (ATP), to specific amino acid residues within a protein. This modification is catalyzed by enzymes known as kinases, while phosphatases reverse the process by removing the phosphate group. Phosphorylation can induce significant changes in the protein’s function, activity, localization, or interactions with other molecules. For instance, it can activate or deactivate enzymes, alter protein stability, or influence signal transduction pathways by modulating protein-protein interactions. This dynamic and reversible process is integral to many cellular functions, including cell division, growth, differentiation, and response to external stimuli. Phosphorylation is also involved in various diseases, such as cancer, where dysregulated phosphorylation can lead to uncontrolled cell proliferation and survival. Which one of these amino acids cannot be phosphorylated?
