Phosphomimetic amino acids
WebPhosphomimetics are amino acid substitutions that mimic a phosphorylated protein, thereby activating 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. WebDec 22, 1998 · To investigate the effect of phosphorylation on IRP1 function, S138 was mutated to the phosphomimetic amino acids aspartate (S138D) or glutamate (S138E) or to nonphosphorylatable alanine (S138A), and the resulting IRP1s were analyzed for function after expression in aconitase-deficient ( aco1) yeast, which are glutamate auxotrophs ( 32 ).
