Glutathione 72-83 Met4p Saccharomyces cerevisiae S288C 38-42 29514209-3 2018 In this study, a competitive O. polymorpha glutathione producer was constructed by overexpression of the GSH2 gene, encoding gamma-glutamylcysteine synthetase, the first enzyme involved in glutathione biosynthesis, and the MET4 gene coding for central regulator of sulfur metabolism. Glutathione 43-54 Met4p Saccharomyces cerevisiae S288C 223-227 29514209-3 2018 In this study, a competitive O. polymorpha glutathione producer was constructed by overexpression of the GSH2 gene, encoding gamma-glutamylcysteine synthetase, the first enzyme involved in glutathione biosynthesis, and the MET4 gene coding for central regulator of sulfur metabolism. Glutathione 189-200 Met4p Saccharomyces cerevisiae S288C 223-227 29514209-4 2018 Overexpression of MET4 gene in the background of overexpressed GSH2 gene resulted in 5-fold increased glutathione production during shake flask cultivation as compared to the wild-type strain, reaching 2167 mg L-1. Glutathione 102-113 Met4p Saccharomyces cerevisiae S288C 18-22 29514209-6 2018 Obtained results suggest involvement of Met4 transcriptional activator in regulation of GSH synthesis in the methylotrophic yeast O. polymorpha. Glutathione 88-91 Met4p Saccharomyces cerevisiae S288C 40-44 17327492-8 2007 Taken together, our data reveal that arsenite-exposed cells channel a large part of assimilated sulfur into glutathione biosynthesis, and we provide evidence that the transcriptional regulators Yap1p and Met4p control this response in concert. Glutathione 108-119 Met4p Saccharomyces cerevisiae S288C 204-209 15689486-6 2005 Cadmium-activated Met4 induced glutathione biosynthesis as well as genes involved in sulfuramino acid synthesis. Glutathione 31-42 Met4p Saccharomyces cerevisiae S288C 18-22 14514673-0 2003 Coupling of the transcriptional regulation of glutathione biosynthesis to the availability of glutathione and methionine via the Met4 and Yap1 transcription factors. Glutathione 46-57 Met4p Saccharomyces cerevisiae S288C 129-133 14514673-0 2003 Coupling of the transcriptional regulation of glutathione biosynthesis to the availability of glutathione and methionine via the Met4 and Yap1 transcription factors. Glutathione 94-105 Met4p Saccharomyces cerevisiae S288C 129-133 14514673-2 2003 Here, we show that the Yap1 and Met4 transcription factors regulate the expression of gamma-glutamylcysteine synthetase (GSH1), encoding the rate-limiting enzyme in glutathione biosynthesis to prevent the damaging effects of glutathione depletion. Glutathione 165-176 Met4p Saccharomyces cerevisiae S288C 32-36 14514673-2 2003 Here, we show that the Yap1 and Met4 transcription factors regulate the expression of gamma-glutamylcysteine synthetase (GSH1), encoding the rate-limiting enzyme in glutathione biosynthesis to prevent the damaging effects of glutathione depletion. Glutathione 225-236 Met4p Saccharomyces cerevisiae S288C 32-36 14514673-6 2003 In contrast, the Yap1-mediated effect is unaffected, indicating that Met4 acts via Cbf1 to regulate the Yap1-mediated induction of GSH1 expression in response to glutathione depletion. Glutathione 162-173 Met4p Saccharomyces cerevisiae S288C 69-73 14514673-9 2003 These results indicate that the Yap1-dependent activation of GSH1 expression in response to glutathione depletion is regulated by the sulfur status of the cell through a specific Met4-dependent mechanism. Glutathione 92-103 Met4p Saccharomyces cerevisiae S288C 179-183 12406228-0 2002 Glutathione regulates the expression of gamma-glutamylcysteine synthetase via the Met4 transcription factor. Glutathione 0-11 Met4p Saccharomyces cerevisiae S288C 82-86 12406228-7 2002 Furthermore, this mechanism normally operates to regulate GSH biosynthesis in the cell, as GSH1 promoter activity is induced in a Met4-dependent manner in a gsh1 mutant which is devoid of GSH, and the addition of exogenous GSH represses GSH1 expression. Glutathione 58-61 Met4p Saccharomyces cerevisiae S288C 130-134 12406228-7 2002 Furthermore, this mechanism normally operates to regulate GSH biosynthesis in the cell, as GSH1 promoter activity is induced in a Met4-dependent manner in a gsh1 mutant which is devoid of GSH, and the addition of exogenous GSH represses GSH1 expression. Glutathione 91-94 Met4p Saccharomyces cerevisiae S288C 130-134 12406228-7 2002 Furthermore, this mechanism normally operates to regulate GSH biosynthesis in the cell, as GSH1 promoter activity is induced in a Met4-dependent manner in a gsh1 mutant which is devoid of GSH, and the addition of exogenous GSH represses GSH1 expression. Glutathione 91-94 Met4p Saccharomyces cerevisiae S288C 130-134 12406228-10 2002 In summary, GSH biosynthesis is regulated in parallel with sulphate assimilation by activity of the Met4 protein, but GSH1-specific mechanisms exist that respond to GSH availability.
