Effect of lignin content on a GH11 endoxylanase acting on glucuronoarabinoxylan-lignin nanocomposites

► Nanocomposites of xylan-model lignin were reconstituted in vitro. ► Nanocomposites with increased lignin content had different particle sizes. ► GH11 xylanase action on xylan was negatively correlated with lignin content of nanocomposites.
