Monoclonal Antibodies to the Alternative Oxidase of Higher Plant Mitochondria

Abstract

The higher plant mitochondrial electron transport chain con- tains, in addition to the cytochrome chain which terminates with cytochrome oxidase, an altemative pathway that terminates with an altemative oxidase. The alternative oxidase of Sauromatum guttatum Schott has recently been identified as a cluster of proteins with apparent M, of 37, 36, and 35 kilodaltons (kD).
