Iron and 2-oxoglutarate (Fe/2OG) enzymes are found in all kingdoms of life and catalyze a broad array of oxidative transformations. Herein, we demonstrate that the activity of an Fe/2OG enzyme can be redirected when changing the targeted carbon hybridization from sp3 to sp2. During leucine 5-hydroxylase catalysis, installation of an olefin group onto the substrate redirects the Fe(IV)-oxo species reactivity from hydroxylation to asymmetric epoxidation. The resulting epoxide subsequently undergoes intramolecular cyclization to form the substituted piperidine, 2S,5S-hydroxypipecolic acid.}, number={21}, journal={BIOCHEMISTRY}, publisher={American Chemical Society (ACS)}, author={Cha, Lide and Milikisiyants, Sergey and Davidson, Madison and Xue, Shan and Smirnova, Tatyana I and Smirnov, Alex I and Guo, Yisong and Chang, Wei-Chen}, year={2020}, month={Jun}, pages={1961–1965} }

In this study, we showed that these enzymes can accommodate leucine isomers and catalyze regiospecific hydroxylation. On the basis of these results, as a proof-of-concept, we demonstrated that the outcome of the reaction can be redirected by installation of an assisting group within the substrate. Specifically, instead of canonical hydroxylation, these enzymes can catalyze non-native nitrile group installation when an azido group is introduced. The reaction is likely to proceed through C-H bond activation by an Fe(IV)-oxo species, followed by azido-directed C≡N bond formation. These results offer a unique opportunity to investigate and expand the reaction repertoire of Fe/2OG enzymes.}, number={8}, journal={JOURNAL OF THE AMERICAN CHEMICAL SOCIETY}, author={Davidson, Madison and McNamee, Meredith and Fan, Ruixi and Guo, Yisong and Chang, Wei-chen}, year={2019}, month={Feb}, pages={3419–3423} }
