Photocaged serine
WebIn another example, Chen et al. synthesized two-photonactivatable chemokine CCL5 using photocaged serine through efficient one-pot total chemical synthesis. The chemical groups at serine residues successfully caged the hCCL5 activity, which allowed a spatiotemporally controlled photoactivation of the chemokine activity [ 22 ]. WebPhotocaged serine is used to control when the target serine is regenerated and phosphorylated. This strategy will likely be used to light-activate other enzymes of interest in living cells provided that enzymatic function is dependent on just one or a few residues of the protein. Another useful application could be the decaging of ...
