| 1 | IMSM_104830 | Fig1_2hour | Saccharomyces cerevisiae | 4932 | Metabolites from S.cerevisiae cells grown in different conditions | S. cerevisiae cultures were grown in synthetic defined minimal medium over 2-hours. At specific time points, equal numbers of cells (~2x10^7) were rapidly harvested and immediately quenched by plunging them into an extraction buffer of 60% methanol. | Metabolites | Estimates of relative amino acid biosynthetic flux in synthetic medium | 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. |

At 2hours, 1 ml of culture was collected and centrifuged for 5 minutes at 7000 rpm at room temperature to pellet the cells.

The cell-free supernatant was mixed with 75% ethanol to extract extracellular amino acids. The mixture was vortexed for 1.0 minute and placed on ice for a few minutes. Samples were then centrifuged at 16000 rpm for 12 minutes at room temperature. 750 µl of the resulting clear supernatant was transferred to new tubes and dried using a speed vacuum. Dried metabolites were stored at -80°C prior to LC-MS/MS analysis. |
