Phosphomimetics are amino acid substitutions that mimic a phosphorylated protein, thereby activating (or deactivating) the protein. Within 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-phosphoryla… WebDec 1, 2005 · The PTPs are a diverse family of enzymes involved in key signaling pathways and implicated in a number of disease states including cancer and diabetes. 5, 6 Currently, PTP activity is followed through the use of small, non-peptidic substrates such as para -nitrophenylphosphate ( p -NPP), 4-methylumbelliferone phosphate (MUP), and …
