Abstract

Background: Lytic polysaccharide monooxygenases (LPMOs) exhibit a copper center that binds dioxygen for catalysis. Results: We present LPMO structures from Cu(II) to Cu(I) and analyze the transition with quantum mechanical calculations. Conclusion: Reduction changes the copper coordination state but requires only minor structural and electronic changes. Significance: These structures provide insight into LPMO catalytic activation for further mechanistic studies.
