Description

Yaoyun Wu and colleagues report a 2026 journal article on an enzyme rebuilt from an ancient ancestor that runs two normally separate chemical reactions in one pocket. Industry often converts amines into esters, a two-step job that nature splits between two enzyme families. The team used ancestral sequence reconstruction, inferring an extinct protein's code from living relatives.

Their rebuilt enzyme, AncFO-221, chains amine oxidation straight into the oxygen-insertion step, making a continuous cycle rather than a loose cascade. Guided by that mechanism, engineering produced a variant with about eighteen-fold better efficiency and near-complete suppression of side reactions. Lactone yields reached ninety-three percent, and the enzyme could be tuned to break the classical rule for which group migrates.
