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 ...
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 ...
