Naringenin 7-O-methyltransferase

Template:Short description Template:Infobox enzyme Naringenin 7-O-methyltransferase (Template:EC number, 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:

S-adenosyl-L-methionine + (2S)-naringenin $\rightleftharpoons$ 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.
