N-methylanthranilic acid
+ SAH
 

This is a methylation reaction in which the anthranilic acid is converted to N-methylanthranilic acid. The methyl group comes from the cofactor, S-adenosyl methionine (SAM), which becomes S-adenosyl-L-homocysteine (SAH). The enzyme was characterised from Ruta graveolens.[1]

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:anthranilate N-methyltransferase. It is also called anthranilic acid N-methyltransferase.[2] The reaction is the first step specific to the biosynthesis of acridone alkaloids.[1]
