In this work, a team led by Dr. Marc Garcia-Borràs report a computationally driven approach to access enantiodivergent enzymatic carbene N–H insertions catalyzed by P411 enzymes. Computational modeling, carried out by PhD student Carla Calvó-Tusell, was employed to rationally guide engineering efforts to control the accessible conformations of a key lactone-carbene (LAC) intermediate in the
