The family of redoxins includes several groups of redox enzymes related to thioredoxins (AllFam:AF023), (Pfam:PF00085): peroxiredoxins, thioredoxins and glutaredoxins. Peroxiredoxins constitute a family of thiol peroxidases that reduce hydrogen peroxide, peroxinitrite, and hydroperoxides using a strictly conserved cysteine. Chloroplast thioredoxin systems in plants regulate the enzymes involved in photosynthetic carbon assimilation. It is thought that redoxins have a large role in anti-oxidant defence.
