Before therapy nitrogen-starved cells were collected by centrifugation and resuspended in fresh nitrogen starvation medium supplemented with 10 M CuSO4 and preincubated for 30 min at 30 for mild induction of myc-Ubi expression (complete induction of CUP1 promoter is generally achieved by 100 M CuSO4; Helliwell et al., 2001). Right after this pre-incubation cells had been exposed to the nitrogen sources under study. Nitrogen-starved yeast cells (40 OD600 units) exposed for various instances towards the corresponding nitrogen compound were harvested by centrifugation and washed twice in distilled water plus 10 mM sodium azide. All subsequent actions had been carried out at 4 . Cell pellets have been suspended in 200 l of BRD2 manufacturer extraction buffer [0.1 M Tris-HCl (pH 7.5)-0.15 M NaCl-5 mM EDTA (pH eight.0), plus a mixture of protease inhibitors (Full; Roche); 1 mM phenylmethylsulphonyl fluoride (PMSF) and 25 mM freshly ready N-ethylmaleimide to prevent artefactual deubiquitination].Development assayNitrogen-starved glucose-repressed cells had been diluted to an OD600 of 0.1 in fresh nitrogen starvation medium containing 4 glucose, supplemented with five mM of your indicated amino acid. Development was measured through automated OD600 measurements utilizing a BioscreenC apparatus (Labsystems). Serial 110 dilutions from an initial 0.5 OD600 ml-1 had been spotted on two agar plates from the identical medium but containing 1 instead of 5 mM from the indicated amino acid.2014 The Authors. Molecular Microbiology published by John Wiley Sons Ltd., Molecular Microbiology, 93, 213Analogues uncouple transceptor functionsCells were broken with glass beads along with the resulting homogenate was centrifuged at 3000 r.p.m. for three min to get rid of unbroken cells and debris. The supernatant was collected and centrifuged for 60 min at 13 000 g. The resulting (P13) pellet was suspended in 400 l of extraction buffer plus 5 M urea, incubated at 0 for 30 min, and centrifuged for 60 min at 13 000 g. The protein pellets have been then suspended in 320 l of extraction buffer plus 80 l of 50 trichloroacetic acid. Immediately after incubation at 0 for 30 min, the samples were centrifuged for 60 min at 13 000 g. The TCA protein precipitates had been then neutralized in 25 l of 1 M Tris base plus 25 l of 2sample buffer [100 mM Tris-HCl, pH 6.8, 4 mM EDTA, 4 sodium dodecyl sulphate (SDS), 20 glycerol, 0.002 bromophenol blue] containing 0.1 M DTT and heated at 37 for 15 min. Aliquots of these plasma membrane-enriched fractions had been analysed by Western blot as described below. For Western blot detection of Gap1, purified monoclonal, horseradish peroxidase-(HRP)-conjugated anti-GFP rabbit antibody (Miltenyi Biotec), or primary polyclonal rabbit antiGap1 antibody (kindly provided by B. Andr Brussels) had been employed. Gap1 key antibody was detected with horseradish peroxidase-conjugated anti-rabbit antibodies (Amersham) (Rubio-Texeira et al., 2012). Normalization from the P13 fractions was accomplished determined by detection of Pma1 with goat polyclonal anti-Pma1 antibody (yN-20; Santa Cruz Biotechnology) detected in turn by HRP-coupled donkey anti-goat IgG, sc-2020 (Santa Cruz Biotechnology).
