Graphical Abstract
A photocatalyst ([Ru(bpy)3]2+) bound to a protein ligand was essential for the title method. Local single-electron transfer from the catalyst resulted in the formation of tyrosyl radicals. N′-Acetyl-N,N-dimethyl-1,4-phenylenediamine was used as the tyrosyl radical trapping agent and used in a radical addition to afford selective modification of the target protein.

- 28The use of lower amounts of compound 3 resulted in lower labeling efficiency owing to the tight binding of compound 3 to CA.
- 29We examined the CA inhibitory activity of compounds 3, 4 and [Ru(bpy)3]Cl2 according to the literature protocol reported by J. A. Verpoorte, S. Mehta, J. T. Edsall, J. Biol. Chem. 1967, 242, 4221–4229. Compound 3 showed higher CA inhibitory activity (IC50: 0.50 μM) than compound 4 (IC50: 1.6 μM). [Ru(bpy)3]Cl2 did not show a significant inhibition at 10 μM. See Figure S9 in the Supporting Information.
- 30We examined the selective modification of CA in mouse erythrocyte lysates at various concentrations of LSC 3 and found that the selectivity of the modification at 1 μM was higher than that at 10 μm, although the modification efficiency dropped. Therefore, we carried out the further CA-selective modification experiments in mouse erythrocyte lysates at 1 μM of 3.
