A mutant (nit8) with a lowered activity of glutamine synthetase (GS) was isolated in Aspergillus nidulans. The levels of GS and of an arginine catabolic enzyme, ornithine transaminase (OTA) were assayed under a variety of growth conditions leading to repression, depression and induction of OTA in the wild type, nit8 and several regulatory mutants. The results obtained appear to exclude the possibility of involvement of GS in the regulation of arginine catabolism in A. nidulans.
