Article Title: Link between light and fatty acid synthesis: Thioredoxin-linked reductive activation of plastidic acetyl-CoA carboxylase
doi:
Figure Lengend Snippet: Effects of thiol reagents on the ACCase activity. ( A ) ACCase activity was measured in the indicated concentration of a thiol reagent as described in Materials and Methods . Plastidic ACCase from pea, continuous lines; cytosolic ACCase from pea, dashed line. β-SH, 2-mercaptoethanol; GSH, reduced form of glutathione. Lipoic acid was dissolved into 50 mM Tricine⋅KOH (pH 8) containing 1 mM phenylmethylsulfonyl fluoride, 1 mM benzamide, and 5 mM ɛ-amino-n-caproic acid at 20 mM, and 0–7 μl of 20 mM solution was added to 13-μl reaction mixture. The activity without any thiol reagent was 11 nmol/20 min per mg of protein for pea plastidic ACCase and 210 nmol/20 min per mg of protein for pea cytosolic ACCase. The activity is relative to that without a thiol reagent, taken to be 1. Results are the means of duplicate determinations that differed less than 10%. ( B ) The effects of preincubation of plastidic ACCase with DTT on activity were examined. Changes with time are shown. After the enzyme was incubated at 30°C for 10 min with 2 mM DTT, the reaction was started by the addition of buffer, ATP, MgCl 2 , KCl, acetyl-CoA, and NaH 14 CO 3 . The final concentrations of these reagents were the same as above. The final concentration of DTT was 1 mM.

Figure Lengend Snippet: Effect of CdTe QDs of different sizes on autophagy in yeast at different time points. Notes: Cells transformed with a plasmid encoding GFP-Atg8 were treated with ( A ) 50 nmol/L CdTe QDs or 100 ng/mL rapamycin or ( B ) phenylmethanesulfonyl fluoride (PMSF), which was added at 0 hour and 16 hours to reach a final concentration of 2 mmol/L, and photographed at 4 hours, 8 hours, 16 hours, and 42 hours using fluorescence microscopy. Scale bars: 5 µm. Abbreviations: CdTe QDs, cadmium telluride quantum dots; G-CdTe, green-emitting CdTe; O-CdTe, orange-emitting CdTe.
