Regulation of Saccharomyces cerevisiae ornithine decarboxylase expression in response to polyamine.
The mechanism of yeast ornithine decarboxylase (ODC) regulation in response to polyamines was examined. ODC catalyzes the first step of polyamine biosynthesis, the conversion of ornithine to putrescine. ODC activity was modulated approximately 200-fold by varying the availability of polyamines. Variations in ODC activity were associated with parallel changes in the amount of active enzyme molec...

متن کاملRegulation of mating in the cell cycle of Saccharomyces cerevisiae
The capacity of haploid a yeast cells to mate (fuse with a haploid strain of alpha mating type followed by nuclear fusion to produce a diploid cell) was assessed for a variety of temperature-sensitive cell division cycle (cdc) mutants at the permissive and restrictive temperatures. Asynchronous populations of some mutants do not mate at the restrictive temperature, and these mutants define gene...
متن کاملRegulation of Saccharomyces cerevisiae CDC7 function during the cell cycle.
The yeast Cdc7 function is required for the G1/S transition and is dependent on passage through START, a point controlled by the Cdc28/cdc2/p34 protein kinase. CDC7 encodes a protein kinase activity, and we now show that this kinase activity varies in the cell cycle but that protein levels appear to remain constant. We present several lines of evidence that periodic activation of CDC7 kinase is...
متن کاملGlucose regulation of Saccharomyces cerevisiae cell cycle genes.
Nutrient-limited Saccharomyces cerevisiae cells rapidly resume proliferative growth when transferred into glucose medium. This is preceded by a rapid increase in CLN3, BCK2, and CDC28 mRNAs encoding cell cycle regulatory proteins that promote progress through Start. We have tested the ability of mutations in known glucose signaling pathways to block glucose induction of CLN3, BCK2, and CDC28. W...
