Glossary: (2S)-naringenin = (2S)-5,7,4′-trihydroxyflavan-4-one
(2S)-sakuranetin = (2S)-5,4′-dihydroxy-7-methoxyflavan-4-one
Other name(s): NOMT
Systematic name: S-adenosyl-L-methionine:(2S)-5,7,4′-trihydroxyflavanone 7-O-methyltransferase
Comments: The enzyme is involved in the biosynthesis of the sakuranetin, an inducible defense mechanism of the plant Oryza sativa (Asian rice) against pathogen attack.
