A cis-dominant regulatory mutation linked to the argB-argC gene cluster in Saccharomyces cerevisiae.
Abstract The argB-argC gene cluster of Saccharomyces cerevisiae , a genetic unit of coordinate expression, is presented as a good tool for investigating the possibility of eucaryotic cells producingExpand

The complete DNA sequence of yeast chromosome III
The entire DNA sequence of chromosome III of the yeast Saccharomyces cerevisiae has been determined. This is the first complete sequence analysis of an entire chromosome from any organism. TheExpand

Multiplicity of the amino acid permeases in Saccharomyces cerevisiae. IV. Evidence for a general amino acid permease.
Kinetic and genetic evidences are presented to show that, in addition to specific amino acid permeases, Saccharomyces cerevisiae has a general amino acid permease which catalyzes the transport ofExpand

GAP1, the general amino acid permease gene of Saccharomyces cerevisiae. Nucleotide sequence, protein similarity with the other bakers yeast amino acid permeases, and nitrogen catabolite repression.
In Saccharomyces cerevisiae, mutations at the GAP1 locus selectively abolish the activity of the general amino acid transport system. This permease catalyses active transport of apparently allExpand

Nitrogen catabolite repression in yeasts and filamentous fungi.
Publisher Summary This chapter provides a brief description of nitrogen catabolite repression in Saccharomyces cerevisiae. The ancestral use of yeasts in industry has led to the selection of manyExpand

Phenylalanine- and tyrosine-auxotrophic mutants of Saccharomyces cerevisiae impaired in transamination
Abstract This paper reports the first isolation of Saccharomyces cerevisiae mutants lacking aromatic aminotransferase I activity (aro8), and of aro8 aro9 double mutants which are auxotrophic for bothExpand

Methylamine/ammonia uptake systems in Saccharomyces cerevisiae: multiplicity and regulation
SummaryThree lines of evidence show that the uptake of methylamine/ammonia in Saccharomyces cerevisiae is mediated by at least two functionally distinct mechanisms.1.Lineweaver-Burk plots forExpand

Nitrogen catabolite regulation of proline permease in Saccharomyces cerevisiae. Cloning of the PUT4 gene and study of PUT4 RNA levels in wild-type and mutant strains.
The proline permease gene PUT4 has been cloned. Nitrogen-source regulation ('ammonia sensitivity') of this and at least two other amino-acid permeases is believed to occur at two distinct levels,Expand
