GDH3 encodes a glutamate dehydrogenase isozyme, a previously unrecognized route for glutamate biosynthesis in Saccharomyces cerevisiae
TLDR
The results indicate that GDH3 plays a significant physiological role, providing glutamate when GDH1 and GLT1 are impaired, the first example of a microorganism possessing three pathways for glutamate biosynthesis.
Saccharomyces cerevisiae has a single glutamate synthase gene coding for a plant-like high-molecular-weight polypeptide
TLDR
The results show that S. cerevisiae has a single NADH-GOGAT enzyme, consisting of three 199-kDa monomers, that differs from the one found in prokaryotic microorganisms but is similar to those found in other eukaryotic organisms such as alfalfa.
Genetic rearrangements of a Rhizobium phaseoli symbiotic plasmid
TLDR
Different structural changes of the Sym plasmid were found in a Rhizobium phaseoli strain that loses its symbiotic phenotype at a high frequency, and in some cases they modified the expression of the bacterium's nodulation ability.
Genetic characterization of Mexican Frankia strains nodulating Casuarina equisetifolia
There is a need to increase the utilization of the Casuarina equisetifolia J.R. Forst. & G. Forst. - Frankia symbiosis and be sure of its effectiveness in Mexico. This may be facilitated by selecti...
Glutamine synthesis is a regulatory signal controlling glucose catabolism in Saccharomyces cerevisiae
TLDR
It is proposed that glutamine biosynthesis plays a role in the regulation of glucose catabolism in Saccharomyces cerevisiae.
Regulation of the amino acid permeases in nitrogen‐limited continuous cultures of the yeast Saccharomyces cerevisiae
TLDR
The results indicate that the nitrogen regulation of the general and the specific amino acid carriers is coordinated in such a way that no redundancy exists in amino acid transport.
Cloning of a yeast gene coding for the glutamate synthase small subunit (GUS2) by complementation of Saccharomyces cerevisiae and Escherichia coli glutamate auxotrophs
TLDR
A Saccharomyces cerevisiae glutamate auxotroph, lacking NADP‐glutamate dehydrogenase (NADP‐GDH) and glutamate synthase (GOGAT) activities, was complemented with a yeast genomic library and data show that the structural gene coding for the yeast small subunit (GUS2) is cloned.
Tyrosine is involved in protection from oxidative stress in Saccharomyces cerevisiae.
TLDR
It is proposed that tyrosine plays a role in the protection against oxidative stress in Saccharomyces cerevisiae and this mutant was unable to withstand the oxidative stress generated by aerobic metabolism.
NADP+-dependent glutamate dehydrogenase activity is impaired in mutants of Saccharomyces cerevisiae that lack aconitase.
A mutant of Saccharomyces cerevisiae lacking aconitase did not grow on minimal medium (MM) and had five- to tenfold less NADP+-dependent glutamate dehydrogenase (GDH) activity than the wild-type,

A Saccharomyces cerevisiae glutamate auxotroph, lacking NADP-glutamate dehydrogenase (NADP-GDH) and glutamate synthase (GOGAT) activities, was complemented with a yeast genomic library and data show that the structural gene coding for the yeast small subunit (GUS2) is cloned.
