The expression of the melanin operon (melC) of Streptomyces antibioticus requires the chaperone-like protein MelC1 for the incorporation of two copper ions (designated as CuA and CuB) and the secretion of the apotyrosinase (MelC2) via a transient bin

Manganese peroxidase (MnP), an extracellular heme enzyme from the lignin-degrading basidiomycetous fungus, Phanerochaete chrysosporium, catalyzes the oxidation of MnII to MnIII. The latter, acting as a diffusible redox mediator, is capable of oxidizi
