Naringenin 7-O-methyltransferase (, NOMT) (full systematic name S-adenosyl-L-methionine:(2S)-5,7,4'-trihydroxyflavanone 7-O-methyltransferase) is a methyltransferase isolated from rice, which catalyzes the biosynthesis of sakuranetin.
This enzyme catalyses the following chemical reaction:
While the enzyme is not present in healthy rice leaves, it can be induced by treatment with ultraviolet radiation, jasmonic acid and copper chloride.
