Enzyme Information
| 2.1.1.65 |
Licodione 2'-O-methyltransferase.
based on mapping to UniProt P93324
S-adenosyl-L-methionine + licodione = S-adenosyl-L-homocysteine + 2'-O- methyllicodione.
-!- As well as licodione (1-(2,4-dihydroxyphenyl)-3-(4-hydroxyphenyl)- 1,3-propanedione), the 2''-hydroxy-derivative and isoliquiritigenin can act as acceptors, more slowly.
|
| 2.1.1.154 |
Isoliquiritigenin 2'-O-methyltransferase.
based on mapping to UniProt P93324
S-adenosyl-L-methionine + isoliquiritigenin = S-adenosyl-L-homocysteine + 2'-O-methylisoliquiritigenin.
-!- Not identical to EC 2.1.1.65. -!- While EC 2.1.1.154 can use licodione as a substrate, EC 2.1.1.65 cannot use isoliquiritigenin as a substrate.
