Antimycin A- and hydroxamate-insensitive respiration in yeasts

Abstract

In this paper evidence is presented for the mitochondrial localization of the antimycin A (AA) + salicylhydroxamate (SHAM)-insensitive respiration of the yeasts Kluyveromyces lactis, Endomycopsis capsularis and Hansenula saturnus. Such a respiration, which can be sustained by NADH and NADPH but not by succinate, is inhibited by high concentrations of azide. AA + SHAM-insensitive respiration is not phosphorylating and its postulated physiological role is to oxidize NADH.
