TLDR
The present review provides exhaustive information of bacterial laccases reported till date including sources, production conditions, characterization, cloning and biotechnological applications needed for the effective understanding and application of these enzymes at the industrial level.Abstract:
Laccases (benzenediol: oxygen oxidoreductase, EC 1.10.3.2) are multi-copper enzymes which catalyze the oxidation of a wide range of phenolic and non-phenolic aromatic compounds in the presence or absence of a mediator. Till date, laccases have mostly been isolated from fungi and plants, whereas laccase from bacteria has not been well studied. Bacterial laccases have several unique properties that are not characteristics of fungal laccases such as stability at high temperature and high pH. Bacteria produce these enzymes either extracellularly or intracellularly and their activity is in a wide range of temperature and pH. It has application in pulp biobleaching, bioremediation, textile dye decolorization, pollutant degradation, biosensors, etc. Hence, comprehensive information including sources, production conditions, characterization, cloning and biotechnological applications is needed for the effective understanding and application of these enzymes at the industrial level. The present review provides exhaustive information of bacterial laccases reported till date.read more

Multicopper Oxidases and Oxygenases
TL;DR: Copper sites have historically been divided into three classes based on their spectroscopic features, which reflect the geometric and electronic structure of the active site: type 1 or blue copper, type 2 (T2) or normal copper, and type 3 (T3) or coupled binuclear copper centers.

Phenolic Compounds: Structure, Classification, and Antioxidant Power
TL;DR: The most common in vitro methods used to evaluate antioxidant activity of phenolic compounds are in-vitro methods which are based on single electron transfer reaction or single hydrogen atom transfer reaction as mentioned in this paper.

Copper coordination in blue proteins.
TL;DR: The lowered reorganization energy in the protein, which is attributable to constrained coordination, is critically important for function, since the driving forces for electron transfer often are low between blue copper centers and distant (>10 Å) donors and acceptors.
