Abstract

Potato tuber mitochondria oxidizing malate respond to NAD+ addition with increased oxidation rates, whereas mung bean hypocotyl mitochondria do not. This is traced to a low endogenous content of NAD+ in potato mitochondria, which prove to take up added NAD+. This mechanism concentrates NAD+ in the matrix space. Analyses for oxaloacetate and pyruvate (with pyruvate dehydrogenase blocked) are consistent with regulation of malate oxidation by the internal NAD+/NADH ratio.
