Phusion® High fidelity DNA polymerase, Taq DNA polymerase, restriction enzymes and T4 DNA ligase were from New England Biolabs (Ozyme, Saint-Quentin-en-Yvelines, France). dNTPs were from Eurogentec (Seraing, Belgium). Plasmids were sequenced by Beckman Coulter Genomics (Grenoble, France). Bacterial and fungus

culture media were from Difco (Detroit, MI, USA). Glutathione Sepharose™ 4B was from GE Healthcare Bio-Sciences AB (Uppsala, Sweden). Lysozyme and reduced and oxidized L-Glutathione were from Sigma-Aldrich Chimie SARL (Saint-Quentin Fallavier, France). SDS-PAGE gels were made with proteomics grade NEXT GEL 12.5% acrylamide solution from AMRESCO (Solon, OH, USA). PageBlue™ protein staining solution and PageRuler™ (cat. #SM0671) protein molecular size markers were from Fermentas (Thermo Electron SAS, Villebon sur Yvette, France). QIAquick Gel Extraction Kit was employed for purifying PCR products from gels. Pirfenidone Plasmid extraction was done with QIAprep Spin Miniprep kit (Qiagen SAS, Courtaboeuf, France). Chemical substrates

were purchased at highest available purity from Sigma-Aldrich Chimie SARL (Saint-Quentin-Fallavier, France). Unless otherwise specified, all other products were from Sigma-Aldrich Chimie SARL. Protein concentration was determined with the Bio-Rad Protein Assay (Bio-Rad, Marnes-la-Coquette, France) Everolimus price based on the Bradford method [38] using bovine serum albumin as calibration standard. Crude and purified protein extracts were analyzed by SDS-PAGE and visualised by Coomassie blue staining. Strain and growth conditions The white-rot basidiomycete Phanerochaete chrysosporium Pregnenolone BKM-F-1767 strain used in this study (CBS 481.73) was purchased from Centraalbureau voor Schimmelcultures (Utrecht, Netherlands) in the form of a freeze-dried fungal culture. The mycelium was inoculated on freshly prepared Difco™ Potato Dextrose Agar (PDA) plates and incubated at 37°C for four days before storage and maintenance at 4°C on PDA plates or at −80°C in 30% glycerol for long-term

preservation. Spore suspensions were prepared after 4-days propagation at 37°C on PDA plates by washing the agar surface with 10 mL of 50 mM sodium acetate buffer at pH 4.5. Spore counts were determined with a counting chamber Thoma double cell. To induce AAD1 expression in P. chrysosporium, 600 mL of Nitrogen-limited liquid medium was inoculated at 104 spores.mL-1 in a 1 L Erlenmeyer flask and cultivated at 37°C and 150 rpm on a TR-225 rotary shaker (Infors AG, Bottmingen, Switzerland) for 1 week. The medium was composed of basal elements, trace elements and vitamins according to [39–41]: (a) Basal elements: Glucose 56 mM, Ammonium tartrate 1.19 mM, KH2PO4 7.35 mM, MgSO4·7H20 2.02 mM, CaC12·2H20 0.68 mM, FeSO4·7H20 6.47 × 10−2 mM, Nitrilotriacetate 7.85 μM; (b) Trace elements: MnSO4·H20 5.92 μM, CoC12·6H20 4.20 μM, ZnSO4·7H20 10.4 μM, CuSO4·5H20 0.04 μM, AlK(SO4)2 2.
