ThTP (top) and ATP synthesis
(bottom) by brain mitochondria are
blocked by the same concentrations of the complex III
inhibitor myxothiazol. The DTMF was incubated for 15
min in the presence of Pi (5 mm), succinate
(5 mm), and various concentrations of myxothiazol. No
ThDP was present. For ATP synthesis, ADP (0.2 mm) was
present, and the incubation time was 10 min (means ±
S.D., n = 2–8).
