Research of Multicopper Oxidase and Its Degradation of Histamine in Lactiplantibacillus plantarum LPZN19

Microorganisms, 2023
In order to explore the structural changes and products of histamine degradation by multicopper oxidase (MCO) in Lactiplantibacillus plantarum LPZN19, a 1500 bp MCO gene in L. plantarum LPZN19 was cloned, and the recombinant MCO was expressed in E.

Role of the Multicopper Oxidase CueO in Copper Homeostasis Under Anaerobic Conditions in Enterobacteria. [PDF]

Mol Microbiol
The periplasmic multicopper oxidase CueO plays a crucial role in copper detoxification in enterobacteria. CueO contains a catalytic site, the Cu‐T1 center, and a methionine‐rich (Met‐rich) domain capable of binding copper.

Transient Absorption Spectroscopy of Blue Copper Sites in Divergent Protein Folds: Azurin Versus Multicopper Oxidase. [PDF]

Chemphyschem
Ultrafast pump‐probe spectroscopy of two evolutionarily divergent blue copper proteins reveals distinct low‐frequency ground‐state collective modes (38 cm−1 in SLAC, 29 cm−1 in azurin) generated via impulsive stimulated Raman scattering, potentially reflecting the differences in the rigidity of the surrounding protein scaffold beyond a conserved Cu ...
