## Abstract Enzymic cleavage of Nβglycosidic bonds of AMP, GMP, and inosine by the cellβfree extracts of __Neurospora crassa__ has been studied. The enzymic activities with these substrates appear to be discrete from one another. The levels of these enzymes in the cell vary with age, and are depend
Mycelia of Neurospora crassa growing with quite different rates at a given temperature (30 ~ C) are obtained by changing the composition of the culture medium: for instance a duplication time of 220 min is found when cultures are growing in Vogel's minimal medium supplemented with glycerol and one o
Neurospora crassa can utilize various purine bases such as xanthine or uric acid and their catabolic products as a nitrogen source. The early purine catabolic enzymes in this organism are regulated by induction and by ammonium repression. Studies were undertaken to investigate purine base transport
