Figure 3. The energy-dependent RET maintains the reduced state of mitochondrial pyridine nucleotides (A) and the steady-state level of NAD(P)H fluorescence of larval midgut homogenate (LMH; B) affected by protonophoric uncoupler FCCP, by the natural hydrolysate of the Cry11Bb protoxin (HC) and by the peptides derived from the Cry11Bb protoxin.

The LMH, in the equivalent of 12 guts, was added to 1 ml SKPH medium. Energy-dependent THG; I, II, III, IV, respiratory chain complexes. Suc., 2.5 mM succinate; FCCP, 1 μM FCCP; CN, 0.5 mM KCN; HC, 57 μg/ml of Cry11Bb hydrolysed in the larval gut extract. The final peptide concentration was 1 μM.
