Yeast oxidative stress response
Aerobic organisms are constantly exposed to reactive oxygen species (ROS), generated as normal metabolism byproducts, especially by respiration [1,2]. To modulate ROS concentrations and to counteract their deleterious effects, there are several antioxidant systems with an apparent functional redundancy, which may provide an evolutionary advantage. Saccharomyces cerevisiae cells possess multiple...
متن کاملYeast transcription factors.
Studies of yeast transcription factors have contributed greatly to understanding basic molecular mechanisms of eukaryotic gene regulation, largely due to powerful genetic approaches that are unavailable in other organisms. The broad outlines of these mechanisms are fairly well understood, and there is an increasing number of examples where detailed information is available.
متن کاملEffect of Environmental Stress Factors and Recycling on the Lipid Composition of Brewer’s Yeast Mitochondria
The aim of this study was to investigate alterations in the content and composition of mitochondrial lipids of brewer’s yeast, which occur during brewing and repetitive recycling. The bottom-fermenting brewer’s yeast of Saccharomyces cerevisiae species obtained from industrial beer production was used throughout the study. The first three generations of recycled yeast were analysed. Differences...
متن کاملGenetic factors that regulate the attenuation of the general stress response of yeast.
The general stress response of yeast involves the induction of approximately 200 genes in response to any one of several stresses. These genes are activated by Msn2 and repressed by the Srb10 kinase, a member of the mediator complex. Normally, Msn2 is exported from the nucleus, and Srb10 represses STRE gene expression. Under stress, Msn2 relocalizes to the nucleus and, with the relief of Srb10 ...
متن کاملMembrane-association of mRNA decapping factors is independent of stress in budding yeast
Recent evidence has suggested that the degradation of mRNA occurs on translating ribosomes or alternatively within RNA granules called P bodies, which are aggregates whose core constituents are mRNA decay proteins and RNA. In this study, we examined the mRNA decapping proteins, Dcp1, Dcp2, and Dhh1, using subcellular fractionation. We found that decapping factors co-sediment in the polysome fra...
