EC 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.
