The GLN3 gene product is required for transcriptional activation of allantoin system gene expression in Saccharomyces cerevisiae.

We show that mutation at the GLN3 locus results in decreased steady-state levels of DAL7, DUR1,2, CAR1, and URA3 mRNAs derived from cultures grown in the presence of inducer. Basal levels of these RNA species, however, were not significantly affected by a gln3 mutation. The GLN3 product appears to affect gene expression in two ways. The pleiotropic… (More)
