KEGG ENZYME: 2.1.1.273

ENZYME: 2.1.1.273

Entry

EC 2.1.1.273                Enzyme

Name

benzoate O-methyltransferase;
BAMT;
S-adenosyl-L-methionine:benzoic acid carboxyl methyltransferase

Class

Transferases;
Transferring one-carbon groups;
Methyltransferases

Sysname

S-adenosyl-L-methionine:benzoate O-methyltransferase

Reaction(IUBMB)

S-adenosyl-L-methionine + benzoate = S-adenosyl-L-homocysteine + methyl benzoate [RN:R10447]

Reaction(KEGG)

R10447

Substrate

S-adenosyl-L-methionine [CPD:C00019];
benzoate [CPD:C00180]

Product

S-adenosyl-L-homocysteine [CPD:C00021];
methyl benzoate [CPD:C20645]

Comment

While the enzyme from the plant Zea mays is specific for benzoate [6], the enzymes from Arabidopsis species and Clarkia breweri also catalyse the reaction of EC 2.1.1.274, salicylate 1-O-methyltransferase [1,5]. In snapdragon (Antirrhinum majus) two isoforms are found, one specific for benzoate [2,3] and one that is also active towards salicylate [4]. The volatile product is an important scent compound in some flowering species [2].
