The effect of calcium and inhibitors on corn mitochondrial respiration.

Abstract

The effects of KCN, antimycin A, malonate, rotenone, and amytal on the oxidation of malate, succinate, and extramitochondrial reduced nicotinamide adenosine dinucleotide (NADH) by corn mitochondria were studied. Potassium cyanide and antimycin A inhibited the oxidation of all three substrates. Rotenone and amytal inhibited only the oxidation of malate, and malonate inhibited only the oxidation of succinate. Rotenone, amytal, and malonate did not inhibit the oxidation of extramitochondrial NADH. The calcium stimulation of the oxidation of extramitochondrial NADH was prevented by KCN and antimycin A but not by amytal, rotenone, or malonate. It is suggested that corn mitochondria possess a flavoprotein specific for extramitochondrial NADH and that this flavoprotein is sensitive to divalent cations.
