Thioredoxin Enzyme System (TRX)

Target
TRX
Molecular classification
Enzyme, Oxidoreductase
01

Overview

The thioredoxin enzyme system (TRX) is a central cellular antioxidant and redox regulatory system. It consists of thioredoxin (Trx), thioredoxin reductase (TrxR), and NADPH. This system plays a crucial role in maintaining the cellular redox environment, defending against oxidative stress, and regulating various biological processes through its disulfide reductase activity. Targeting the bacterial TRX systems is a potential strategy for developing new antibiotics.

02

Mechanism of action

Inhibition of thioredoxin reductase by binding to key cysteine/selenocysteine residues, disrupting the electron transfer chain from NADPH to thioredoxin and subsequent reduction of target proteins.
