The lid dictates: An aminomutase was converted into an ammonia lyase by a rational single-point mutation that destabilizes the closed conformation of the lid covering the active site. The resulting aromatic β-amino acid converting lyase exhibited significantly increased reaction rates (44-fold) and was applied in a preparative-scale asymmetric amination reaction and in kinetic resolution for the production of β-phenylalanine.
