Mode of operation and low-resolution structure of a multi-domain and hyperthermophilic endo-β-1,3-glucanase from Thermotoga petrophila

► Mode of operation of specific endo β-1-3 acting glucanase. ► Biophysical characterization over laminarase hyperthermophilicity. ► Low resolution determination by small angle X-ray of a V-shape laminarase.
