Thus, the two substrates of this enzyme are S-adenosyl methionine and (indol-3-yl)pyruvate, whereas its two products are S-adenosylhomocysteine and (3S)-3-(indol-3-yl)-3-oxobutanoate.
Nomenclature
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: (indol-3-yl)pyruvate C-methyltransferase. Other names in common use include indolepyruvate methyltransferase, indolepyruvate 3-methyltransferase, indolepyruvic acid methyltransferase, and S-adenosyl-L-methionine:indolepyruvate C-methyltransferase. This enzyme participates in tryptophan metabolism.
