The peroxisomal catalase gene in the methylotrophic yeast Pichia methanolica.
In this paper, we describe the CTA1 gene, which encodes a peroxisomal catalase in the methylotrophic yeast Pichia methanolica. The P. methanolica CTA1 gene (PmCTA1) comprises a 1,530-bp open reading frame corresponding to a protein of 510 amino acid residues, and its deduced amino acid sequence shows high similarity to those of Cta1ps from other methylotrophic yeasts (about 79%). Expression of ...
متن کاملA missense mutation in the heavy subunit of gamma-glutamylcysteine synthetase gene causes hemolytic anemia.
gamma-Glutamylcysteine synthetase (GCS) catalyzes the initial and rate-limiting step in the biosynthesis of glutathione. gamma-GCS consists of a heavy and a light subunit encoded by separate genes. Hereditary deficiency of GCS has been reported in 6 patients with hemolytic anemia and low erythrocyte levels of glutathione and gamma-glutamylcysteine. In addition, 2 patients also had generalized a...
متن کاملGamma-glutamylcysteine synthetase deficiency and hemolytic anemia.
gamma-Glutamylcysteine synthetase is one of the enzymes of glutathione (GSH) synthesis. A deficiency of this enzyme has been found only once previously in humans: it was associated with spinocerebellar degeneration and hemolytic anemia. We report the case of a woman, daughter of fifth cousins, who was gamma-glutamylcysteine-synthetase-deficient. Modest decreases in the amount of GSH in cultured...
متن کاملRegulation of the gene encoding glutathione synthetase from the fission yeast.
The fission yeast cells that contained the cloned glutathione synthetase (GS) gene showed 1.4-fold higher glutathione (GSH) content and 1.9-fold higher GS activity than the cells without the cloned GS gene. Interestingly, gamma-glutamylcysteine synthetase activity increased 2.1-fold in the S. pombe cells that contained the cloned GS gene. The S. pombe cells that harbored the multicopy-number pl...
متن کاملRegulation and physiological role of the DAS1 gene, encoding dihydroxyacetone synthase, in the methylotrophic yeast Candida boidinii.
The physiological role of dihydroxyacetone synthase (DHAS) in Candida boidinii was evaluated at the molecular level. The DAS1 gene, encoding DHAS, was cloned from the host genome, and regulation of its expression by various carbon and nitrogen sources was analyzed. Western and Northern analyses revealed that DAS1 expression was regulated mainly at the mRNA level. The regulatory pattern of DHAS ...
