Enhancement of Thermal Stabilization of Formaldehyde Dehydrogenase from Pseudomonas putida by Directed Evolution

抄録

We used directed evolution to enhance the thermostability of formaldehyde dehydrogenase from Pseudomonas putida. At 50 °C, the wild-type enzyme was inactivated within 30 min, but the variants obtained retained 80% activity for at least 300 min. At room temperature (30 °C), the variants obtained retained <80% activity for at least 500 h (21 d).
