KEGG   ENZYME: 2.1.1.341
Entry
EC 2.1.1.341                Enzyme                                 

Name
vanillate/3-O-methylgallate O-demethylase;
ligM (gene name)
Class
Transferases;
Transferring one-carbon groups;
Methyltransferases
Sysname
vanillate:tetrahydrofolate O-methyltransferase
Reaction(IUBMB)
(1) vanillate + tetrahydrofolate = protocatechuate + 5-methyltetrahydrofolate [RN:R10136];
(2) 3-O-methylgallate + tetrahydrofolate = gallate + 5-methyltetrahydrofolate [RN:R09271]
Reaction(KEGG)
R09271 R10136
Substrate
vanillate [CPD:C06672];
tetrahydrofolate [CPD:C00101];
3-O-methylgallate [CPD:C05616]
Product
protocatechuate [CPD:C00230];
5-methyltetrahydrofolate [CPD:C00440];
gallate [CPD:C01424]
Comment
The enzyme, characterized from the bacterium Sphingomonas sp. SYK6, is involved in the degradation of lignin. The enzyme has similar activities with vanillate and 3-O-methylgallate.
