Abstract

SUMMARY: The activity of the NADP-linked glutamate dehydrogenase (GDH) increased in the pileus during sporophore development but remained at a low level in the parent mycelium and in the sporophore stipe. In contrast, the NAD-linked enzyme (GDH) increased in mycelium, stipe and pileus. It is suggested that the increase in GDH activity is a developmental phenomenon. In vegetative mycelia the two GDH enzymes appeared to be regulated reciprocally; GDHwas subject to catabolite repression and urea derepression, while GDH was catabolite derepressed and repressed by urea. It is suggested that GDH may be the enzyme normally involved in ammonia assimilation, GDH being reserved for specific functions associated with developmental alterations in metabolism.
