The multifaceted nature of peroxiredoxins in chemical biology
Current opinion in chemical biology, 2023•Elsevier
Abstract Peroxiredoxins (Prx), thiol-dependent peroxidases, were first identified as H 2 O 2
detoxifiers, and more recently as H 2 O 2 sensors, intermediates in redox-signaling
pathways, metabolism modulators, and chaperones. The multifaceted nature of Prx is not
only dependent on their peroxidase activity but also strongly associated with specific protein–
protein interactions that are being identified, and where the Prx oligomerization dynamics
plays a role. Their oxidation by a peroxide substrate forms a sulfenic acid that opens a route …

Abstract
Peroxiredoxins (Prx), thiol-dependent peroxidases, were first identified as H2O2 detoxifiers, and more recently as H2O2 sensors, intermediates in redox-signaling pathways, metabolism modulators, and chaperones.
The multifaceted nature of Prx is not only dependent on their peroxidase activity but also strongly associated with specific protein–protein interactions that are being identified, and where the Prx oligomerization dynamics plays a role. Their oxidation by a peroxide substrate forms a sulfenic acid that opens a route to channel the redox signal to diverse protein targets.
Recent research underscores the importance of different Prx isoforms in the cellular processes behind disease development with potential therapeutic applications.
