A hybrid myoglobin, containing a single‐stranded DNA anchor and a redox‐active ruthenium moiety tethered to the heme center can be used as a photocatalyst. The catalyst can be selectively immobilized on a surface‐bound complementary DNA molecule and thus readily recycled from complex reaction mixtures. This principle may be applied to a range of heme‐dependent enzymes allowing the generation of novel light‐triggered photocatalysts. Photoactivatable myoglobin containing a DNA oligonucleotide as a structural anchor was designed by using the reconstitution of artificial heme moieties containing Ru3+ ions. This semisynthetic DNA–enzyme conjugate was successfully used for the oxidation of peroxidase substrates by using visible light instead of H2O2 for the activation. The DNA anchor was utilized for the immobilization of the enzyme on the surface of magnetic microbeads. Enzyme activity measurements not only indicated undisturbed biofunctionality of the tethered DNA but also enabled magnetic separation‐based enrichment and recycling of the photoactivatable biocatalyst.
