| 3.1.1.117 | more |
in nature, the enzyme hydrolyses ester bonds between aliphatic alcohols in lignin and the 4-O-methyl-D-glucuronic acid side chains of xylan |
| 3.1.1.117 | more |
the enzyme can target ester linkages that contribute to lignin-carbohydrate complexes that form in plant cell walls. Glucuronoxylan is characterized by a beta-1,4 linked xylose backbone that can be substituted by alpha-(1,2)-glucopyranosyl uronic acid (GlcA) or 4-O-methyl-alpha-D-glucopyranosyl uronic acid (MeGlcA) side groups. In gymnosperms, glucuronoxylan can be substituted with alpha-(1,2)-L-arabinose, while glucuronoxylans in angiosperms is acetylated |
| 3.1.1.117 | more |
the enzyme cleaves the ester linkage between lignin alcohols and xylan-bound 4-O-methyl-D-glucuronic acid of hemicellulose |
| 3.1.1.117 | more |
the enzyme hydrolyzes the ester linkage between the 4-O-methyl-D-glucuronic acid of glucuronoxylan and lignin alcohols |
