Recently laccase has been expressed in the Now, after almost 140 years of research, it seems that this copper-containing protein with a number of unique catalytic properties is widely distributed across all kingdoms of life. However, this can lead to a lack of important nutrients and vitamins such as calcium, vitamin D, riboflavin and protein. Lactose that has not been digested by human lactase will be digested by bacterial lactase. In fungi, laccases appear more than the higher plants. Johnson AC, Pendergast TH 4th, Chaluvadi S, Bennetzen JL, Devos KM.

[/ICCBased 3 0 R] >> rized by unique domain consisting of several conserved cystine, aromatic A fungal metabolite mediates degradation of non-phenolic lignin structures and synthetic lignin by laccase. FOIA Schematic representation of the molecular evolution of laccases (based on Komori and Higuchi [11] and Nakamura and Go [16]). ABSTRACT- Laccase is multicopper oxidases that are widely distributed among plants, insects, fungi and bacteria. Laccases have received attention of researchers in the last few decades due to their ability to oxidize both phenolic and nonphenolic lignin-related compounds as well as highly recalcitrant environmental pollutants.
