Entry

EC 2.1.1.49                 Enzyme

Name

amine N-methyltransferase;
nicotine N-methyltransferase;
tryptamine N-methyltransferase;
arylamine N-methyltransferase;
tryptamine methyltransferase

Class

Transferases;
Transferring one-carbon groups;
Methyltransferases

Sysname

S-adenosyl-L-methionine:amine N-methyltransferase

Reaction(IUBMB)

S-adenosyl-L-methionine + an amine = S-adenosyl-L-homocysteine + a methylated amine [RN:R02808]

Reaction(KEGG)

R02808 > R02174 R02910;
(other) R08537

Substrate

S-adenosyl-L-methionine [CPD:C00019];
amine [CPD:C00706]

Product

S-adenosyl-L-homocysteine [CPD:C00021];
methylated amine [CPD:C02436]

Comment

An enzyme of very broad specificity; many primary, secondary and tertiary amines can act as acceptors, including tryptamine, aniline, nicotine and a variety of drugs and other xenobiotics.
