Abstract
Bioeconomy requires sustainable sources of biomass (e.g. chitin and cellulose) to use as energy, feed and biomaterials. In the quest of biomass conversion, lytic polysaccharide monooxygenases (LPMOs) are key enzymatic players. To exploit the full potential of LPMOs, a functional and structural understanding is crucial. In this thesis, we have used the unique versatility of nuclear magnetic resonance (NMR) spectroscopy to characterize and better understand key aspects of LPMO functionality; including their structural features, the effect of copper on LPMO structure and substrate interactions, the molecular basis of their substrate binding, the location of the electron transfer event, their dynamic features, and the role of LPMO-associated carbohydrate-binding modules (CBMs).
