Functional Families

Overview of the Structural Clusters (SC) and Functional Families within this CATH Superfamily. Clusters with a representative structure are represented by a filled circle.

Superfamily: Alternative oxidase

Members of this superfamily share the structure of the cyanide-insensitive alternative oxidase (AOX) found in all higher plants, some algae, yeasts, molds, metazoans, and pathogenic microorganisms such as Trypanosoma brucei. AOX is a diiron carboxylate protein that catalyzes the four-electron reduction of dioxygen to water by ubiquinol PMID:23487766.

This enzyme was first identified as a distinct oxidase pathway from cytochrome c oxidase as the alternative oxidase is resistant to inhibition by the poison cyanide PMID:1883834.
