Peroxiredoxins
peroxiredoxins
Peroxiredoxins (Prxs, EC 1.11.1.15 ) are a ubiquitous family of antioxidant enzymes that also control cytokine -induced peroxide levels and thereby mediate signal transduction in mammalian cells. The physiological importance of peroxiredoxins is illustrated by their relative abundance (one of the most abundant proteins in erythrocytes after hemoglobin is peroxiredoxin 2).
