EC 2.1.1.91

Accepted name: isobutyraldoxime O-methyltransferase

Reaction: S-adenosyl-L-methionine + 2-methylpropanal oxime = S-adenosyl-L-homocysteine + 2-methylpropanal O-methyloxime

Other name(s): aldoxime methyltransferase; S-adenosylmethionine:aldoxime O-methyltransferase; aldoxime O-methyltransferase

Systematic name: S-adenosyl-L-methionine:2-methylpropanal-oxime O-methyltransferase

Comments: Oximes of C4 to C6 aldehydes can act as acceptors; the most active substrate is 2-methylbutyroaldoxime.
