Capped and gowned: A two‐step approach can be used to site‐specifically modify the 5′‐cap of eukaryotic mRNAs. First, a trimethylguanosinesynthase variant recognizes the m7G cap structure and introduces bioorthogonal groups using S‐adenosyl‐L‐methionine‐based cosubstrates. Then, the enzymatically introduced reporter groups are further modified by thiol–ene or CuAAC click chemistry (see scheme).
