Study TitleComparative metabolomics analysis of two Saccharomyces cerevisiae strains: the wild type and mtl1Δ, which carries a deletion of the mechanosensor Mtl1p (part-II)
Study SummaryTo gather more in-depth knowledge of the Mtl1p mechanosensor's role in Saccharomyces cerevisiae metabolism, we conducted a comparative metabolomic analysis of two Saccharomyces cerevisiae strains: the wild type and mtl1Δ, which carries a deletion of the mechanosensor Mtl1p. Both strains were grown under normal conditions at 27°C. The most significant metabolic changes between these strains were related to amino acid metabolism, purine metabolism, and carboxylic acid metabolism.

Sample Preparation:

Sampleprep ID:SP001695
Sampleprep Summary:Extraction of metabolites was performed by homogenization in 1 mL of cold methanol/H2O (1:1) extraction solution and centrifugated at 167 x g at 4°C for 5 min. Supernatants were collected and evaporated to dryness in a nitrogen stream stream at 50 ºC (RapidVap, Labconco), and derivatized by methoxyamination by adding 50 μl of 20 mg/ml solution of methoxyamine hydrochloride in pyridine followed by incubation at 37°C for 2 hours. Trimethylsilylation was subsequently performed by adding 50 µl of N-methyl-N-trimethylsilyl-trifluoroacetamide (MSTFA+1% TMCS) and incubated for 1 hour at 65°C. Samples were centrifuged at 13000 rpm for 10 minutes at RT. Supernatants were transferred to glass vials for GC/MS analysis
