A novel laccase from Tricholoma mongolicum was purified by using a procedure which entailed ion exchange chromatography on DEAE-cellulose, CM-cellulose, Q-Sepharose, and FPLC-gel filtration on Superdex 75. The purified enzyme was obtained with a specific activity of 1480 U/mg-protein and a final yield of 15%. It was found to be a monomeric protein with a(More)
A 59 kDa laccase with inhibitory activity against HIV-1 reverse transcriptase (IC(50) = 2.4 μM) was isolated from the broth of mycelial culture of the mushroom Lentinus tigrinus. The isolation procedure involved ion exchange chromatography on DEAE-cellulose and CM-cellulose, and gel filtration by fast protein liquid chromatography on Superdex 75. The(More)
A 33.5-kDa serine protease designated as helvellisin was isolated from dried fruiting bodies of the wild ascomycete mushroom Helvella lacunosa. It was purified by using a procedure which entailed ion exchange chromatography on DEAE-cellulose, CM-Sepharose, Q-Sepharose, and FPLC-gel filtration on Superdex 75. The protease was characterized by unique(More)
A 14.6-kDa RNase, with a pH optimum of 5.5 and a temperature optimum of 70 °C, was isolated from dried fruiting bodies of the edible mushroom Lactarius flavidulus. The purification procedure involved, in succession, ion exchange chromatography on DEAE-cellulose, CM-cellulose and SP-Sepharose, and finally FPLC-gel filtration on Superdex 75. The RNase was(More)
A special component is isolated from Semen sinapis Albae (white mustard seed), a traditional Chinese medicine. According to the physical and chemical investigation and spectroscopic identification, this component can be known as p-hydroxybenzoylcholine bisulfate, a choline base. This component in the drug is also determined by RP-HPLC. A reversed-phase(More)
A monomeric feruloyl esterase (FAE) with a molecular mass of 62 kDa was acquired from fresh fruiting bodies of the edible mushroom Russula virescens. The isolation procedure involved ion exchange chromatography on CM-cellulose, Q-Sepharose, and SP-Sepharose and finally fast protein liquid chromatography-gel filtration on Superdex 75. Two amino acid(More)
An RNase with a molecular mass of 28 kDa and with high ribonucleolytic activity toward poly(A) was purified from the ascocarps of Tuber indicum. The purification procedure involved ion exchange chromatography on diethylaminoethyl cellulose, Q-Sepharose and Mono Q, and gel filtration by fast protein liquid chromatography on Superdex 75. The pH and(More)
A ribonuclease, with a molecular mass of 22.5 kDa and an N-terminal sequence exhibiting resemblance to previously isolated buckwheat storage proteins and allergens, was isolated from Japanese large brown buckwheat seeds. The ribonuclease was purified using a simple protocol that comprised ion exchange chromatography on Q-Sepharose and DEAE-cellulose and gel(More)
Six strains of crown gall bacteria were isolated from flowering cherry. It was revealed by Otten paper electrophoresis that of the six strains, only BYH18-4 possessed the octopine type Ti plasmid, the remainder having nopaline type Ti plasmid. BYH5-1 was identified by physiological and biochemical tests to be Agrobacterium tumefaciens (originally biovar 1).(More)
During Agaricus bisporus cultivation, lignocellulose degradation is the result of the activity of both the mushroom and microbial communities developed during the composting. To investigate the lignocellulose degradation in detail from the beginning to the end of the process, the functional groups of cellulose, hemicellulose, and lignin have been studied(More)
