Project description:Expression profiles of 110 the central metabolism-related enzymes were obtained by the selected reaction monitoring (SRM) assay methods using LC-MS/MS from the wild type (BY4742), a GCR2 gene deletion strain, and 29 single-gene deletion strains lacking enzyme genes responsible for central carbon metabolism (including CIT1, ENO1, FBP1, GCR2, GND1, GPD1, GPM2, HOR2, HXK1, HXK2, IDH1, IDH2, IDP1, LPD1, MAE1, MDH1, MDH2, PDA1, PDC1, PFK1, PYC2, RPE1, TAL1, TDH1, TDH2, TDH3, TKL1, TPS1, TPS2, and ZWF1 genes).
The central carbon metabolism is strictly controlled by modulation of enzyme expressions to maintain an essential system of living organisms. In this study, metabolic safety mechanisms in the model organism, Saccharomyces cerevisiae, were investigated by direct determination of enzyme expression levels. Targeted proteome analysis of 31 S. cerevisiae wild type and mutant strains revealed that at least 30% of the observed variations in enzyme expression levels could be explained by global regulatory mechanisms. Co-expression analysis revealed that expression levels of enzymes involved in trehalose metabolism and glycolysis changed in a coordinated manner under the control of the transcription factors for global regulation.
Project description:This dataset consists of 784 non-responsive mutants (three or less significant mRNA expression changes as a result of the deletion) from a gene expression profile compendium of 1,484 deletion mutants that have a role or are implicated in mRNA transcription regulation, mRNA turnover, signaling or are located in the nucleus.
Project description:This dataset consists of 700 responsive mutants (four or more significant mRNA expression changes as a result of the deletion) from a gene expression profile compendium of 1,484 deletion mutants that have a role or are implicated in mRNA transcription regulation, mRNA turnover, signaling or are located in the nucleus.
