In enzymology, a tabersonine 16-O-methyltransferase (EC 2.1.1.94) is an enzyme that catalyzes the chemical reaction
- S-adenosyl-L-methionine + 16-hydroxytabersonine [math]\displaystyle{ \rightleftharpoons }[/math] S-adenosyl-L-homocysteine + 16-methoxytabersonine
Thus, the two substrates of this enzyme are S-adenosyl methionine and 16-hydroxytabersonine, whereas its two products are S-adenosylhomocysteine and 16-methoxytabersonine.
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:16-hydroxytabersonine 16-O-methyltransferase. Other names in common use include 11-demethyl-17-deacetylvindoline 11-methyltransferase, 11-O-demethyl-17-O-deacetylvindoline O-methyltransferase, S-adenosyl-L-methionine:11-O-demethyl-17-O-deacetylvindoline, and 11-O-methyltransferase. This enzyme participates in terpene indole and ipecac alkaloid biosynthesis.
