Sample Preparation:

Sampleprep ID:SP002279
Sampleprep Summary:Strains were inoculated in 3 ml of TSB containing 14 mM glucose in glass tubes (Fisher Scientific, cat# 14-961-29) for 16 h and adjusted to an OD600 of 0.05 in 50 ml TSB containing 14 mM glucose in 500 ml flasks and grown at 250 rpm, 37oC for 3 h or 6 h. Culture volumes corresponding to OD600 of 10 optical units were harvested and rapidly filtered through a membrane (0.45 μm, Millipore Cat# MIHAWG100) using Microfil® Filtration Funnels (Millipore, Cat# HAWG047S6) and EZ-FITTM Manifold Base, 6 Place Stainless Steel (Millipore, Cat# EZFITBASE6). The cells on the membrane were washed twice with 5 ml of 0.6% saline and then immediately quenched in 5 ml of ice-cold 60% ethanol containing Br-ATP (final concentration 2 μM) as internal control. The cells were mechanically disrupted using 0.1 mm diameter Glass beads (biospec, Cat# 11079101) and bead homogenizer for 30 s at 6,800 rpm, 3 cycles, 10 sec pause, 4oC(Precellys Evolution, bertin technologies) and centrifuged at 13,000 rpm, 10 min at 4oC to remove cell debris. The supernatant containing intracellular metabolites were separated, and 3 ml was added to 17 ml DW, frozen, lyophilized using FreeZone 4.5 Liter (labconco, Catalog #: 720401050), , and stored in a ultra-low temperature freezer set at -80°C until further analysis.
