Uga3 and Uga35/Dal81 transcription factors regulate UGA4 transcription in response to GABA and leucine
(American Society for Microbiology, 2010-08)
The Saccharomyces cerevisiae UGA4 gene encodes a permease capable of importing γ-aminobutyric acid (GABA) and δ-aminolevulinic acid (ALA) into the cell. GABA-dependent induction of this permease requires at least two ...
Constitutive expression of the UGA4 gene in Saccharomyces cerevisiae depends on two positive-acting proteins, Uga3p and Uga35p
(Wiley Blackwell Publishing, Inc, 2000-12)
The first specific precursor of porphyrin biosynthesis is delta-aminolevulinic acid. delta-Aminolevulinic acid enters Saccharomyces cerevisiae cells through the gamma-aminobutyric acid specific permease Uga4p. It was ...
Biomass production and bromatologic of silage to aerial parts of twenty accesses of sweet potato
(Univ Estadual Centro-oeste, 2015-01-01)
The objective of this study was to evaluate the adaptability of 20 accesses of sweet potato as the characteristics of biomass production and physical composition of the plant, as well as the qualitative characteristics of ...
Common features and differences in the expression of the three genes forming the UGA regulon in Saccharomyces cerevisiae
(Academic Press Inc Elsevier Science, 2011-07)
The three genes that form the UGA regulon in Saccharomyces cerevisiae are responsible for the transport and degradation of γ-aminobutyric acid (GABA) in this organism. Despite the differences in the sequence of their ...
Interplay between the transcription factors acting on the GATA- and GABA-responsive elements of Saccharomyces cerevisiae UGA promoters
(Society for General Microbiology, 2012-04)
γ-Aminobutyric acid (GABA) transport and catabolism in Saccharomyces cerevisiae are subject to a complex transcriptional control that depends on the nutritional status of the cells. The expression of the genes that form ...
UGA4 gene encoding the γ-aminobutyric acid permease in Saccharomyces cerevisiae is an acid-expressed gene
(Pergamon-Elsevier Science Ltd, 2001-12)
Background and aims: biological processes in all organisms are controlled by environmental conditions, however, information concerning the molecular responses to external pH is scarce. In this work we studied the pH response ...
Unravelling the transcriptional regulation of saccharomyces cerevisiae UGA genes: The dual role of transcription factor leu3
(Society for General Microbiology, 2017-11)
Yeast cells can use γ-aminobutyric acid (GABA), a non-protein amino acid, as a nitrogen source that is mainly imported by the permease Uga4 and catabolized by the enzymes GABA transaminase and succinate-semialdehyde ...
Regulación de la expresión del gen UGA4 de Saccharomyces cerevisiae: mecanismos moleculares involucrados en la respuesta a los aminoácidos extracelularesRegulation of the Saccharomyces cerevisiae UGA4 gene expression: molecular mechanisms involved in the response to extracellular amino acids

New insights into the regulation of the Saccharomyces cerevisiae UGA54 gene: Two parallel pathways participate in carbon-regulated transcription
(Society for General Microbiology, 2007-11)
The Saccharomyces cerevisiae UGA4 gene, which encodes the γ-aminobutyric acid (GABA) and δ-aminolaevulinic acid (ALA) permease, is well known to be regulated by the nitrogen source. Its expression levels are low in the ...
