Ligninolytic enzymes produced by white-rot fungi are effective degraders of recalcitrant aromatic environmental pollutants. However, gene sequences of these enzymes are rich in CpG dinucleotides, which are particularly unfavorable to efficient expression in plants. In order to develop a phytoremediation technique with a ligninolytic enzyme-producing(More)
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(More)
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(More)
To reduce the risk of the bovine spongiform encephalopathy agent being recycled to cattle through animal feed, in October 2001 Japan introduced a feed ban prohibiting the use of animal proteins in feed. PCR identification of feed ingredients is part of the audit program to ensure the proper implementation of the feed ban. For efficient analysis, screening(More)
Phanerochaete sordida YK-624 is a hyper lignin-degrading basidiomycete possessing greater ligninolytic selectivity than either P. chrysosporium or Trametes versicolor. To construct a gene transformation system for P. sordida YK-624, uracil auxotrophic mutants were generated using a combination of ultraviolet (UV) radiation and 5-fluoroorotate resistance as(More)
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(More)
