New insight into the structure and function of the alternative oxidase.

Biochimica et biophysica acta - 20 Nov 2000

Berthold D A, Andersson M E, Nordlund P

Abstract excerpt

The alternative oxidase is a ubiquinol oxidase found in plant mitochondria, as well as in the mitochondria of some fungi and protists. It catalyzes a cyanide-resistant reduction of oxygen to water without translocation of protons across the inner mitochondrial membrane, and thus functions as a non-energy-conserving member of the respiratory electron transfer chain. The active site of the alternative oxidase has...
