Characterization of multicopper oxidase-related protein and multicopper oxidase-1 in insects
Typical multicopper oxidases (MCOs) have ten conserved histidines and one conserved cysteine that coordinate four copper atoms, which are required for oxidase activity. During our studies of insect MCOs, we discovered a gene that we named multicopper oxidase-related protein (MCORP). MCORPs share …

Laccase-1 in the pea aphid, Acyrthosiphon pisum (Harris)
Laccases belong to the “multicopper oxidase” family of proteins, and can oxidize o-diphenols and p-diphenols in the presence of molecular oxygen. Laccases have been well characterized in wood-rotting fungi where they appear to play a role in lignin degradation, morphogenesis, and stress defense. …

Using Esterase and Laccase Enzymes to Derivatize Bioactive Plant Phenolics for Altered Chemistry
… on long-chain p-nitrophenyl (pNP) esters. A multicopper oxidase (SCO6712) from Streptomyces coelicolor displayed activity on a variety of phenolics including caffeic acid, ferulic acid, resveratrol, quercetin, morin, kaempferol and myricetin. Among the products formed by action on flavonols …

Evolution of copper-containing nitrite reductase
… A crystal structure was solved for a putative multicopper oxidase (MCO) and NiR homologue from Arthrobacter sp. (AMMCO) to 1.8 Å resolution. The overall folds of AMMCO and NiR are very similar (r.m.s.d. of 2.0 Å over 250 Cα atoms); Like NiR, AMMCO is a trimer with type-1 Cu sites in the …

A Novel Manganese Oxidising Bacterium: Characterisation and Genomic Evaluation
… the identification of four candidate manganese oxidase genes of the multicopper oxidase class, tentatively designated mnxG123 and mofA on the basis of homology with these genes within the manganese oxidising bacteria Pseudomonas putida GB-1, Leptothrix cholodnii SP-6 and Leptothrix discophora …

Understanding The Molecular Mechanism Of Manganese Oxidation In Leptothrix Discophora Ss1
… as hypothesized. MofA a putative muticopper oxidase, identified from the oxidizing fraction of Leptothrix discophora SS1 supernatant to encode the manganese oxidizing activity, was deleted from the genome and the cells lacking mofA did not lose the ability to oxidize manganese. This finding …

Oxygen reduction electrocatalysis
… the ORR. The first section focuses on laccase, a multicopper oxidase that catalyzes the four-electron reduction of oxygen to water. Upon adsorption to an electrode surface, laccase is known to reduce oxygen at overpotentials lower than the best noble metal electrocatalysts usually employed. …

Biological and biomimetic oxygen electro-reduction by enzymes
… The SLAC enzyme is a member of the large multicopper oxidase (MCO) family of enzymes that perform oxygen reduction and share a similar 4-copper active site. MCO enzymes are commonly used at the cathode of biofuel cells to catalyze oxygen reduction despite the lack of understanding of the …
