Sysname |
S-adenosyl-L-methionine:catechol O-methyltransferase
|
Reaction(IUBMB) |
S-adenosyl-L-methionine + a catechol = S-adenosyl-L-homocysteine + a guaiacol [RN: R07330]
|
Reaction(KEGG) |
|
Substrate |
|
Product |
S-adenosyl-L-homocysteine [CPD: C00021];
guaiacol [CPD: C15572]
|
Comment |
The mammalian enzyme acts more rapidly on catecholamines such as adrenaline or noradrenaline than on catechols.
