Abstract Enzymes that oxidize aromatic substrates have been harnessed for cell-based technologies including proximity labeling and electron microscopy; however, they are associated with drawbacks such as the need for toxic H2O2. Here, we explore multicopper oxidases (laccases) as a new enzyme class for proximity labeling and electron microscopy in mammalian cells.

Abstract Enzymes that oxidize aromatic substrates have shown utility in a range of cell-based technologies including live cell proximity labeling (PL) and electron microscopy (EM), but are associated with drawbacks such as the need for toxic H2O2. Here, we explore laccases as a novel enzyme class for PL and EM in mammalian cells.
