Engineering Fluoroacetate Dehalogenase by Growth‐Based Selections on Non‐Natural Organofluorides
Angewandte Chemie, EarlyView.We present a high‐throughput selection system to engineer fluoroacetate dehalogenases (FAcDs). By challenging E. coli populations that produce diverse FAcD libraries to grow on non‐natural organofluorides as their sole carbon source, we isolated a panel of FAcD variants with improved activity and altered substrate specificity.
