Lytic polysaccharide monooxygenases and other histidine-brace copper proteins: structure, oxygen activation and biotechnological applications

Johan O. Ipsen et al.

Summary: Lytic polysaccharide monooxygenases (LPMOs) are copper enzymes that catalyze the oxidative cleavage of glycosidic bonds, found in all biological kingdoms and used in industrial biorefineries. However, the introduction of LPMOs poses challenges in industrial reactors and reduces enzyme stability. Further research is needed to understand the interaction between LPMOs and their environments, as well as the molecular mechanisms involved in their function.

Deciphering the oxygen activation mechanism at the CuC site of particulate methane monooxygenase

Wei Peng et al.

Summary: This study deciphers the catalytic cycle of pMMO in the presence of the physiological reductant duroquinol (DQH(2)), revealing that O-2 activation is initiated by the Cu-C(ii)-DQH(-) species. The research also uncovers the important roles of the phenol co-substrate for O-2 activation.

Copper Centers in the Cryo-EM Structure of Particulate Methane Monooxygenase Reveal the Catalytic Machinery of Methane Oxidation

W-H Chang et al.

Summary: The particulate methane monooxygenase (pMMO) is a key enzyme in methanotrophic bacteria that converts methane into methanol. Structural studies have revealed the active site and catalytic mechanism of the enzyme, shedding light on the process of methane oxidation.

Towards a unified understanding of the copper sites in particulate methane monooxygenase: an X-ray absorption spectroscopic investigation†

George E. Cutsail et al.

Summary: The study investigated the enzymatic conversion of methane to methanol by methane monooxygenases (MMOs) under mild conditions. The results revealed the presence of only monocopper sites in particulate MMO (pMMO), contradicting the previous proposed dicopper site. Additionally, photodamage was found to partially contribute to observed features in X-ray absorption spectrum, highlighting the complexity involved in EXAFS measurement and modeling of dilute metalloproteins with multiple metal centers.
