2.1.1.279

Accepted name:

trans-anol O-methyltransferase

Reaction:

(1) S-adenosyl-L-methionine + trans-anol = S-adenosyl-L-homocysteine + trans-anethole
(2) S-adenosyl-L-methionine + isoeugenol = S-adenosyl-L-homocysteine + isomethyleugenol

Glossary:

trans-anol = 4-[(1E)-prop-1-en-1-yl]phenol
trans-anethole = 1-methoxy-4-[(1E)-prop-1-en-1-yl]benzene

Other name(s):

AIMT1; S-adenosyl-L-methionine:t-anol/isoeugenol O-methyltransferase; t-anol O-methyltransferase

Systematic name:

S-adenosyl-L-methionine:trans-anol O-methyltransferase

Comments:

The enzyme from anise (Pimpinella anisum) is highly specific for substrates in which the double bond in the propenyl side chain is located between C₇ and C₈, and, in contrast to EC 2.1.1.146, (iso)eugenol O-methyltransferase, does not have activity with eugenol or chavicol.
