Journal ArticleDOI
Laccases: a never-ending story.
Paola Giardina,Vincenza Faraco,Cinzia Pezzella,Alessandra Piscitelli,Sophie Vanhulle,Giovanni Sannia +5 more
TL;DR: In this review, the most recent studies on laccase structural features and catalytic mechanisms along with analyses of their expression are reported and examined with the aim of contributing to the discussion on their structure–function relationships.
Journal ArticleDOI
Copper induction of laccase isoenzymes in the ligninolytic fungus Pleurotus ostreatus.
TL;DR: An analysis performed with protease inhibitors revealed that the loss of extracellular POXA1b activity could have been due to the presence of specific proteases secreted into the copper-containing culture medium that affected the extraceocytes of the poxa1b isoenzyme.
Journal ArticleDOI
A Novel White Laccase from Pleurotus ostreatus
TL;DR: Two laccase isoenzymes produced by Pleurotus ostreatus were purified and fully characterized, revealing clear homology with laccases from other microorganisms and showing remarkable high stability with respect to both pH and temperature.
Journal ArticleDOI
Induction and transcriptional regulation of laccases in fungi.
Alessandra Piscitelli,Paola Giardina,Vincenzo Lettera,Cinzia Pezzella,Giovanni Sannia,Vincenza Faraco +5 more
TL;DR: Most of the published results on fungal laccase induction, as well as analyses of both the sequences and putative functions of laccases gene promoters are reviewed, suggesting the existence of a complex picture of lAccase regulation phenomena acting through a variety of cis acting elements.
Journal ArticleDOI
Remazol Brilliant Blue R decolourisation by the fungus Pleurotus ostreatus and its oxidative enzymatic system
TL;DR: Decolourisation of the recalcitrant dye Remazol Brilliant Blue R by the fungus basidiomycete Pleurotus ostreatus was investigated and treatment with the laccase mixture reduced its toxicity by 95%.
