Abstract:
- A specific succinate requirement for energy-linked reduction of mitochondrial pyridine nucleotide is demonstrated in pigeon heart and guinea pig kidney mitochondria.
- The succinate used in this reduction can be generated in the oxidation of malate plus glutamate or of α-ketoglutarate.
- The role of succinate is identified by the specific inhibitory responses of the reaction to malonate, phosphate, and fumarate.
- At least two kinds of mitochondrial pyridine nucleotide are shown to be reducible in State 4: (a) about one-third in the absence of added succinate in a malonate-insensitive reaction in the presence of a substrate such as malate plus glutamate and (b) about two-thirds in the presence of added succinate in a malonate-sensitive, energy-linked reaction. These two kinds of pyridine nucleotide may be considered to be compartmented.
