FIG. 7.
Effects of atovaquone on [U-14C]PHBA incorporation into CoQ in P. carinii mitochondrial and microsomal fractions. Circles, mitochondrial fraction; squares, microsomal fraction. Incorporation into the microsomal fraction was inhibited, whereas the drug had no effect on CoQ synthesis in the mitochondrial fraction. Each point represents the mean ± SEM; n = 3.
