Abstract
En 中文
The global demand for amino acids continues to rise, yet traditional synthesis methods face environmental and safety challenges. To contribute to a sustainable future vision, we herein report a novel cofactor-neutral in vitro multienzyme cascade that directly converts methanol, a renewable C1 feedstock, into glycine under mild conditions. A two-step strategy achieves 82.2% methanol-to-glycolaldehyde and 86.0% glycolaldehyde-to-glycine conversion, respectively. At 500 mM methanol, it yields 18.8 mM glycine after 6 h, which represents a 26.8-fold improvement over the one-pot approach. These results demonstrate the potential of modular in vitro multienzyme catalysis for efficient C1-to-amino acid transformation and establish a foundation for the synthesis of many other complex nitrogen-containing molecules.
