FunFam 67: Salicylate/benzoate carboxyl methyltransferase

There are 4 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Benzoate O-methyltransferase. [EC: 2.1.1.273]
S-adenosyl-L-methionine + benzoate = S-adenosyl-L-homocysteine + methyl benzoate.
  • While the enzyme from the plant Zea mays is specific for benzoate, the enzymes from Arabidopsis species and Clarkia breweri also catalyze the reaction of EC 2.1.1.274.
  • In snapdragon (Antirrhinum majus) two isoforms are found, one specific for benzoate and one that is also active toward salicylate.
  • The volatile product is an important scent compound in some flowering species.
 3 D9J100 D9J101 Q6XMI3
Anthranilate O-methyltransferase. [EC: 2.1.1.277]
S-adenosyl-L-methionine + anthranilate = S-adenosyl-L-homocysteine + O-methyl anthranilate.
  • In the plant maize (Zea mays), the isoforms AAMT1 and AAMT2 are specific for anthranilate while AAMT3 also has the activity of EC 2.1.1.273.
 3 B6SU46 D9J0Z7 D9J100
Salicylate carboxymethyltransferase. [EC: 2.1.1.274]
S-adenosyl-L-methionine + salicylate = S-adenosyl-L-homocysteine + methyl salicylate.
  • The enzyme, which is found in flowering plants, also has the activity of EC 2.1.1.273.
  • Formerly EC 2.1.1.n9.
 2 D9J100 Q6XMI3
Jasmonate O-methyltransferase. [EC: 2.1.1.141]
S-adenosyl-L-methionine + jasmonate = S-adenosyl-L-homocysteine + methyl jasmonate.
  • 9,10-dihydrojasmonic acid is a poor substrate for the enzyme.
  • The enzyme does not convert 12-oxo-phytodienoic acid (a precursor of jasmonic acid), salicylic acid, benzoic acid, linolenic acid or cinnamic acid into their corresponding methyl esters.
  • Enzyme activity is inhibited by the presence of divalent cations, e.g., Ca(2+), Cu(2+), Mg(2+) and Zn(2+).
