Regulatory interaction between the respiratory chain of mitochondria and the oxidative system of the endoplasmic reticulum
1978
: A regulation mechanism of the interaction of microsomal oxidases and mitochondrial respiratory chain with oxidase substrates is suggested. Quantitative comparison of their affinity to microsomal oxidases and mitochondrial NADH-dehydrogenase is carried out. The interaction with both systems is found to be hydrophobic. It is found that microsomal oxidase substrates inhibit mitochondrial NADH-dehydrogenase at concentrations, which should completely fill the active site of cytochrome P-450. It is suggested that redistribution of reduced equivalents from mitochondria to microsomes and the acceleration of xenobiotic detoxication take place.
