In [[enzymology]], a '''tryptophan 2-C-methyltransferase''' ({{EC number|2.1.1.106}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:S-adenosyl-L-methionine + L-tryptophan <math>\rightleftharpoons</math> S-adenosyl-L-homocysteine + L-2-methyltryptophan

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[S-Adenosyl methionine|S-adenosyl methionine]] and L-[[tryptophan]], whereas its two [[product (chemistry)|products]] are [[S-adenosylhomocysteine]] and [[L-2-methyltryptophan]].

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:L-tryptophan 2-C-methyltransferase'''. Other names in common use include '''tryptophan 2-methyltransferase''', and '''S-adenosylmethionine:tryptophan 2-methyltransferase'''.
