Fig. 1. Orbital steering in enzyme-catalyzed reactions can lead (A) to properly aligned substrates by maximizing bonding orbital overlaps and minimizing anti-bonding orbital overlaps or can lead^ (B) to improperly aligned substrates if the reaction coordinate^ trajectory is perturbed by modification.
