Abstract
Three different phenol oxidases produced by the basidiomycete fungus Pleurotus ostreatus have been isolated and their main structural, enzymatic and physico-chemical properties characterized. Studies have forcaused on the most abundantly secreated of these proteins, a copper-e nzyme specific towards ortho-diphenol substrates. This protein was purified to homogeneity and part of its primary structure determined by direct protein sequencing. The ingluence of pH, temperature and presence of water-soluible or water-insoluble organic solvents on the activity and stability of the enzyme were also investigated. These data can be used for applying bioarectors to problems of environmental concern such as waste-water treatmentKeywords
