Can tyrosine be phosphorylated
WebWithin cells, proteins are commonly modified at serine, tyrosine and threonine amino acids by adding a phosphate group. Phosphorylation is a common mode of activating or deactivating a protein as a form of regulation. However some non-phosphorylated amino acids appear chemically similar to phosphorylated amino acids. WebThe only amino acids that can be phosphorylated are serine, tyrosine and threonine making this a very specific modification to amino acid chains. It may be necessary for enzymes to …
