FunFam 147: Caffeoyl-CoA O-methyltransferase 1

There are 3 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
Tricin synthase. [EC: 2.1.1.175]
2 S-adenosyl-L-methionine + tricetin = 2 S-adenosyl-L-homocysteine + 3',5'-O-dimethyltricetin.
  • The enzymes from Oryza sativa (ROMT-15 and ROMT-17) catalyzes the stepwise methylation of tricetin to its 3'-mono- and 3',5'-dimethyl ethers.
  • In contrast with the wheat enzyme (EC 2.1.1.167, tricetin 3',4',5'-O- trimethyltransferase), tricetin dimethyl ether is not converted to its 3',4',5'-trimethylated ether derivative.
  • The enzymes from Hordeum vulgare (HvOMT1) and from Zea mays (ZmOMT1) form the 3',5'-dimethyl derivative as the major product.

Caffeoyl-CoA O-methyltransferase. [EC: 2.1.1.104]
S-adenosyl-L-methionine + caffeoyl-CoA = S-adenosyl-L-homocysteine + feruloyl-CoA.

    Flavonoid 3',5'-methyltransferase. [EC: 2.1.1.267]
    (1) S-adenosyl-L-methionine + a 3'-hydroxyflavonoid = S-adenosyl-L- homocysteine + a 3'-methoxyflavonoid. (2) S-adenosyl-L-methionine + a 5'-hydroxy-3'-methoxyflavonoid = S-adenosyl-L-homocysteine + a 3',5'-dimethoxyflavonoid.
    • Isolated from Vitis vinifera (grape).
    • Most active with delphinidin 3-glucoside but also acts on cyanidin 3-glucoside, cyanidin, myricetin, quercetin and quercetin 3-glucoside.
    • The enzyme from Catharanthus roseus was most active with myricetin.
    • Formerly EC 2.1.1.149.
