In [[enzymology]], a '''3-hydroxy-16-methoxy-2,3-dihydrotabersonine N-methyltransferase''' ({{EC number|2.1.1.99}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:S-adenosyl-L-methionine + 3-hydroxy-16-methoxy-2,3-dihydrotabersonine <math>\rightleftharpoons</math> S-adenosyl-L-homocysteine + deacetoxyvindoline

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[S-Adenosyl methionine|S-adenosyl methionine]] and [[3-hydroxy-16-methoxy-2,3-dihydrotabersonine]], whereas its two [[product (chemistry)|products]] are [[S-adenosylhomocysteine]] and [[deacetoxyvindoline]].

This enzyme belongs to the family of [[transferase]]s, specifically those transferring one-carbon group methyltransferases.  The systematic name of this enzyme class is '''S-adenosyl-L-methionine:3-hydroxy-16-methoxy-2,3-dihydrotabersonine N-methyltransferase'''. Other names in common use include '''16-methoxy-2,3-dihydro-3-hydroxytabersonine methyltransferase''', '''NMT''', '''16-methoxy-2,3-dihydro-3-hydroxytabersonine N-methyltransferase''', '''S-adenosyl-L-methionine:16-methoxy-2,3-dihydro-3-hydroxytabersonine''', and '''N-methyltransferase'''.  This enzyme participates in [[indole and ipecac alkaloid biosynthesis]].
