Hydroxynitrile lyases (HNLs) catalyze the enantioselective cleavage/formation of cyanohydrins. However, current methods for determining hydrocyanation are not suitable for mass screening of mutants for protein engineering of these biocatalysts. We demonstrate herein a chromogenic high‐throughput screening method for cyanohydrin synthesis that is validated by either substrate profiling or the directed evolution
