Degradation of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans by the white rot fungus Phanerochaete sordida YK-624.

Cloning and homologous expression of novel lignin peroxidase genes in the white-rot fungus Phanerochaete sordida YK-624.

Two genes, encoding YK-LiP1 and YK-LiP2, were cloned from the white-rot fungus Phanerochaete sordida YK-624, and a homologous expression system for the gene was constructed. Two full-length cDNAs (ylpA and ylpB) were isolated by degenerate RT-PCR and RACE-PCR. The results of N-terminal amino acid sequence analysis of native YK-LiP1 and YK-LiP2 showed that ylpA and ylpB coded for YK-LiP2 and YK-...

Improvement of ligninolytic properties in the hyper lignin-degrading fungus Phanerochaete sordida YK-624 using a novel gene promoter.

We identified a highly expressed protein (BUNA2) by two-dimensional gel electrophoresis from the hyper lignin-degrading fungus Phanerochaete sordida YK-624 under wood-rotting conditions. Partial amino acid sequences of BUNA2 were determined by LC-MS/MS analysis, and BUNA2 gene (bee2) and promoter region were PCR-cloned and sequenced. The bee2 promoter was used to drive the expression of the man...

We characterized a lignin peroxidase (YK-LiP2) isolated from shaking culture inoculated with white-rot fungus Phanerochaete sordida YK-624. YK-LiP2 enzyme was identified and purified to homogeneity by anion-exchange chromatography and gel

Improvement of ligninolytic properties by recombinant expression of glyoxal oxidase gene in hyper lignin-degrading fungus Phanerochaete sordida YK-624.

Glyoxal oxidase (GLOX) is a source of the extracellular H2O2 required for the oxidation reactions catalyzed by the ligninolytic peroxidases. In the present study, the GLOX-encoding gene (glx) of Phanerochaete chrysosporium was cloned, and bee2 promoter of P. sordida YK-624 was used to drive the expression of glx. The expression plasmid was transformed into a P. sordida YK-624 uracil auxotrophic...

Cloning and transcriptional analysis of the gene encoding 5-aminolevulinic acid synthase of the white-rot fungus Phanerochaete sordida YK-624.

In this study, we cloned the gene encoding 5-aminolevulinic acid synthase (ALAS) from the hyper-lignin-degrading fungus Phanerochaete sordida YK-624. The deduced amino acid sequence showed highest identity (93.0%) to ALAS of P. chrysosporium. Expression of the gene encoding ALAS, which we named aas, corresponded temporally with the expression and activity of manganese peroxidase.
