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 ... WebAs serine (or cysteine) at position 1 of the intein is needed for the protein splicing pathway, the usage of a so-called photocaged serine – a serine with a light-removable protecting group (photolabile ‘caging’ group) attached to it – allowed inhibiting splicing by Tli pol-2 intein until UV light liberated the catalytic residue and ...
WebWe have recently reported the direct light activation of TET dioxygenases in cells by the incorporation of 4,5-dimethoxy-2-nitrobenzyl-L-serine (1, Figure 3 a) via amber suppression. 18 We ...
