Abstract

SUMMARY: About 200 forward mutants of Neurospora obtained as suppressors of arg were studied. All fell in the region, and all appeared deficient in aspartic transcarbamylase (ATC) to various degrees: extreme deficiencies in ATC (-N alleles) resulted in pyrimidine-dependence as well as suppression of arg, while partial ATC deficiencies ( lleles) led only to suppression. Five different complementation groups were represented among the -N alleles studied. Evidence is presented which suggests that -N and lleles affect ATC via different mechanisms.
