WebMay 25, 2012 · Various photocaged amino acids are accessible for incorporation, which in turn makes a wide variety of protein gene-regulators accessible for modification. The light-regulation of enzymatic function was achieved through incorporation of photocaged analogues of tyrosine , cysteine , serine , and lysine . In another example, Chen et al. synthesized two-photon-activatable 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].
Webserine (colored in green) is mostly buried inside the proteins core. Therefore, every small change in this area will probably impact dramatically the tertiary structure of the protein. … WebApr 9, 2010 · For example, photocaged cysteine (13), serine (14), lysine (15), and tyrosine (16) derivatives have been site-specifically incorporated into proteins to allow the photodynamic regulation of their activity (15, 37, 38, 39).
