Naringenin 7-O-methyltransferase (EC 2.1.1.232, 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.[1]
This enzyme catalyses the following chemical reaction:
- S-adenosyl-L-methionine + (2S)-naringenin
S-adenosyl-L-homocysteine + (2S)-sakuranetin
While the enzyme is not present in healthy rice leaves, it can be induced by treatment with ultraviolet radiation, jasmonic acid and copper chloride.[1]
