This invention provides an application of the camptothecin oxygen methyltransferase CaOMT3 in catalyzing the oxygen methylation modification of hydroxycamptothecin and quercetin. Through transcriptomic and genomic analysis, four oxygen methyltransferases (CaOMT3) were identified. BECAUSE OF Genes were found to be clustered together; further analysis of metabolite and transcriptome co-expression revealed a gene significantly positively correlated with rhamnine accumulation. BECAUSE OF Genes, that is CaOMT3 Biochemical functional verification showed that CaOMT1, CaOMT2, and CaOMT3 can all catalyze the reaction of 9- and 10-hydroxycamptothecin. O Methylation yields the corresponding methoxycamptothecin. When quercetin is used as a substrate, CaOMT1 and CaOMT3 exhibit bifunctional catalytic activity, capable of simultaneously catalyzing the methylation of the 4'- and 7'-hydroxyl sites. O α-methylation yields rhamnosin, tamarindin, and phytoflavin; while CaOMT2 only catalyzes the 4'-hydroxyl site. Enzymatic kinetic analysis showed that CaOMT3's catalytic efficiency for quercetin ( k cat / K (m) is the highest. This invention provides a new enzyme tool and technological foundation for the synthetic biology research and industrial fermentation production of rhamnine and methoxycamptothecin.
