| EC Number | 3.1.1.117 |
| Enzyme Function | FUNCTION: Glucuronoyl esterase which may play a significant role in biomass degradation, as it is considered to disconnect hemicellulose from lignin through the hydrolysis of the ester bond between 4-O-methyl-D-glucuronic acid residues of glucuronoxylans and aromatic alcohols of lignin. {ECO:0000269|PubMed:22924998, ECO:0000269|PubMed:24997793}. |
