Alanine Represses gamma-Aminobutyric Acid Utilization and Induces Alanine Transaminase Required for Mitochondrial Function in Saccharomyces cerevisiae
Márquez Gutiérrez, Dariel; Escalera-Fanjul, Ximena; El Hafidi, Mohammed; Aguirre López, Beatriz; Riego Ruíz, Lina Raquel; González Manjarrez, María Alicia (Frontiers Media S.A., 2021)"The gamma-aminobutyric acid (GABA) shunt constitutes a conserved metabolic route generating nicotinamide adenine dinucleotide phosphate (NADPH) and regulating stress response in most organisms. Here we show that in the ... -
Diversification of transcriptional regulation determines subfunctionalization of paralogous branched chain aminotransferases in the yeast Saccharomyces cerevisiae
González Flores, James; López, Geovani; Argueta, Stefany; Escalera-Fanjul, Ximena; Hafidi, Mohammed El; Campero Basaldúa, José Carlos; Strauss, Joseph; Riego Ruíz, Lina Raquel; González Manjarrez, María Alicia (Genetics Society of America, 2017)"Saccharomyces cerevisiae harbors BAT1 and BAT2 paralogous genes that encode branched chain aminotransferases and have opposed expression profiles and physiological roles . Accordingly, in primary nitrogen sources such as ... -
In Kluyveromyces lactis a Pair of Paralogous Isozymes Catalyze the First Committed Step of Leucine Biosynthesis in Either the Mitochondria or the Cytosol
Aguirre López, Beatriz; Escalera-Fanjul, Ximena; Hersch González, Jaqueline; Rojas Ortega, Eréndira; El Hafidi, Mohammed; Lezama Barquet, Mijail; González Flores, James; Bianchi, Michele Maria; López Ortiz, Geovani; Márquez Gutiérrez, Dariel; Scazzocchio, Claudio; Riego Ruíz, Lina Raquel; González Manjarrez, María Alicia (Frontiers Media S.A., 2020)"Divergence of paralogous pairs, resulting from gene duplication, plays an important role in the evolution of specialized or novel gene functions. Analysis of selected duplicated pairs has elucidated some of the mechanisms ...
