This invention relates to the field of synthetic biology, specifically to an oxygen methyltransferase and its application in the biosynthesis of isozyridine and aziridine. This application identifies the core gene elements of the isozyridine biosynthetic pathway—the oxygen methyltransferase genes SgOMT3 and Ese08G000662.t1—which encode proteins capable of catalyzing the conversion of fraxinus to isozyridine. Based on the oxygen methyltransferase of this application, combined with the isozyridine metabolic pathway, isozyridine can be synthesized in bacteria, yeast, algae, and plant substrates. This application provides an artificial synthetic pathway for isozyridine, offering a theoretical basis for the efficient, green, and low-carbon production of isozyridine through biosynthesis.
