The ZN domain acts as a dynamic switch coordinating multiple-step aminoacylation in bacterial leucyl-tRNA synthetase
Abstract Aminoacyl-tRNA synthetases (AARSs) safeguard translational fidelity by coordinating amino acid activation and tRNA charging within distinct catalytic and editing domains. In leucyl-tRNA synthetase (LeuRS), the small, centrally located zinc-binding domain (ZN domain) sits at the crossroads of these functional c...
