Title: The Quantitative Amino Acid Economy of Yeast Reveals Public versus Private Goods and Guides Syntrophic Community Design
Summary: Using S. cerevisiae, here we establish an absolute, quantitative blueprint of the intracellular and extracellular amino acid economy, defining the fluxes of production, secretion and consumption across 24 hours of cell growth. The data includes absolute intra and extracellular amino acid amounts, amino acid biosynthetic flux for all amino acids, changes in amino acids in yeast auxotrophic strains, and data on amino acid consumption in cells.

Metabolites Absolute concentrations of intracellular amino acids in the cells across the indicated times of growth NA NA NA NA 3.0 NA

The quenched cells were extracted in 75% ethanol. The mixture was then dried down using a speed vacuum (rotatory evaporator). The dried metabolites were subsequently dissolved in 300 µl of mass spectrometry-grade water, and 10 µl of this sample was injected for targeted LC-MS/MS analysis.
