Fig. 3

Three-dimensional visualisation of protein-ligand binding. Molecular docking protein-ligand poses were visualised and annotated within ChimeraX. Binding residues were identified within Discovery Studio. Non-flexible constructs were compared to flexible chimeras to visualise differences in ligand binding following the addition of GGGGS(x3) hinges. Laccases derive from Fusarium venenatum, Stenotrophomonas acidaminiphila, Salipaludibacillus agaradhaerens, and a novel Stenotrophomonas sp. See Additional file 2 for laccase sequence information. Displayed models are representative of triplicate docking analyses
