Abstrakt: Agaricus bisporus is able to use urate, allantoin, allantoate, urea and alloxanate as nitrogen sources for growth. The presence of urate oxidase, allantoinase, ureidoglycolase and urease activities, both in fruit bodies and mycelia, points to a degradative pathway for urate similar to that found in various microorganisms. So far all efforts to demonstrate the enzyme responsible for allantoate degradation failed. A urease inhibitor appeared to be present in cell-free extracts from fruit bodies.
