Energy-linked Functions of Submitochondrial Particles Prepared from Mung Bean Mitochondria 1

S B Wilson a, W D Bonner Jr a
PMCID: PMC396528  PMID: 16657417

Abstract

Submitochondrial particles from mung bean mitochondria (Phaseolus aureus) are able to catalyze an energy-linked reduced nicotinamide adenine dinucleotide-nicotinamide adenine dinucleotide phosphate transhydrogenase reaction supported by ATP or by aerobically generated high energy intermediates. The energy transfer pathway appears to differ from that utilized for oxidative phosphorylation.

Mung bean submitochondrial particles will also reduce nicotinamide adenine dinucleotide by reversed electron transport from succinate or ascorbate tetramethyl-p-phenylenediamine. The energy requirement can be met by ATP or by aerobically generated high energy intermediates.

A scheme for the energy transduction pathway in mung beans is postulated from the effects of inhibitors and uncouplers of energy transfer on transhydrogenase and reversed electron transfer reactions.
