Indolepyruvate C-methyltransferase (EC 2.1.1.47) is an enzyme that catalyzes the chemical reaction
This is a methylation reaction in which indole-3-pyruvic acid is converted to (R)-3-(indol-3-yl)-2-oxobutyric acid. The methyl group comes from the cofactor, S-adenosyl methionine (SAM), which becomes S-adenosyl-L-homocysteine (SAH).[1][2]

This enzyme is part of the biosynthetic pathway to the indole alkaloid, indolmycin, in Streptomyces griseus[3]
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.[4]
