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 45-kDa ribonuclease (RNase) was purified from dried fruiting bodies of the wild mushroom Amanita hemibapha. It was adsorbed on DEAE-cellulose, S-sepharose, and finally purified on Superdex 75. The RNase exhibited maximal RNase activity at pH 5 and in a temperature range between 60-70°C. It demonstrated no ribonucleolytic activity toward four(More)
