(S)-scoulerine 9-O-methyltransferase

Class of enzymes (S)-scoulerine 9-O-methyltransferase 2.1.1.117 0030777 (S)-scoulerine 9-O-methyltransferase (2.1.1.117) is an enzyme that catalyzes the chemical reaction 65% scoulerine + SAM Q27102599 isocorypalmine + SAH This is a methylation reaction in which the benzylisoquinoline alkaloid, (S)-scoulerine, is converted to (S)-isocorypalmine. The methyl group comes from the cofactor, S-adenosyl methionine (SAM), which becomes S-adenosyl-L-homocysteine (SAH). The enzyme was characterised from Berberis wilsoniae.Muemmler S, Rueffer M, Nagakura N, Zenk MH 1985 S-Adenosyl-L-methionine:(S)-scoulerine 9-O-methyltransferase, a highly stereo- and regiospecific enzyme in tetrahydroberberine biosynthesis Plant Cell Reports 4 1 36–39 10.1007/BF00285501 24253642 http://nbn-resolving.de/urn:nbn:de:bvb:19-epub-3629-3 This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:(S)-scoulerine 9-O-methyltransferase. It is part of the alkaloid biosynthesis pathway.2.1.1.117 References Biology no Category:EC 2.1.1 Category:Enzymes of unknown structure
