Thus, the two substrates of this enzyme are S-adenosyl methionine and 2-methylpropanal oxime, whereas its two products are S-adenosylhomocysteine and 2-methylpropanal O-methyloxime.

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:2-methylpropanal-oxime O-methyltransferase. Other names in common use include aldoxime methyltransferase, S-adenosylmethionine:aldoxime O-methyltransferase, and aldoxime O-methyltransferase.
