Purification and Characterization of Two Novel Laccases from <i>Peniophora lycii</i>
Although, currently, more than 100 laccases have been purified from basidiomycete fungi, the majority of these laccases were obtained from fungi of the Polyporales order, and only scarce data are available about the laccases from other fungi.

| description | Although, currently, more than 100 laccases have been purified from basidiomycete fungi, the majority of these laccases were obtained from fungi of the Polyporales order, and only scarce data are available about the laccases from other fungi. In this article, laccase production by the white-rot basidiomycete fungus <i>Peniophora lycii</i>, belonging to the Russulales order, was investigated. It was shown that, under copper induction, this fungus secreted three different laccase isozymes. Two laccase isozymes—Lac5 and LacA—were purified and their corresponding nucleotide sequences were determined. Both purified laccases were relatively thermostable with periods of half-life at 70 °C of 10 and 8 min for Lac5 and LacA, respectively. The laccases demonstrated the highest activity toward ABTS (97 U·mg<sup>−1</sup> for Lac5 and 121 U·mg<sup>−1</sup> for LacA at pH 4.5); Lac5 demonstrated the lowest activity toward 2,6-DMP (2.5 U·mg<sup>−1</sup> at pH 4.5), while LacA demonstrated this towards gallic acid (1.4 U·mg<sup>−1</sup> at pH 4.5). Both Lac5 and LacA were able to efficiently decolorize such dyes as RBBR and Bromcresol Green. Additionally, phylogenetic relationships among laccases of <i>Peniophora</i> spp. were reconstructed, and groups of orthologous genes were determined. Based on these groups, all currently available data about laccases of <i>Peniophora</i> spp. were systematized. |
