Resumen
Laccase (EC 1.10.3.2; benzenediol:oxygen oxidoreductase) was first discovered
at the end of the 19th century in the sap of Oriental lacquer trees. Later

Laccase (EC 1.10.3.2; benzenediol:oxygen oxidoreductase) was first discovered
at the end of the 19th century in the sap of Oriental lacquer trees. Later
on, the laccase from the white-rot basidiomycete Trametes versicolor was
thoroughly characterized using biochemical and biophysical methods. It is
an extracellular blue multicopper glycoprotein. The copper ions are involved
in the catalytic process, in which a reducing substrate, typically a phenol, is
oxidized and molecular oxygen is reduced to water. Today, a multitude of different
laccases and laccase genes from various sources have been characterized.
The enzyme seems to have different physiological roles in different
types of organisms. Several of the best characterized laccases come from basidiomycete
fungi causing white-rot decay of wood. These laccases are generally
regarded to be associated with the biodegradation of lignin, although
more research is needed to shed light on the fundamental molecular mechanisms.
Recent advances with regard to the structural and functional diversity
of laccases will be discussed in relation to efforts to clarify the physiological
roles of the enzyme and to elucidate its potential in various applications, including
detoxification, bleaching, and analysis. [--]
