Mechanism of actionQuercetin is a specific quinone reductase 2 (QR2) inhibitor, an enzyme (along with the human QR1 homolog) which catalyzes metabolism of toxic quinolines. Inhibition of QR2 in plasmodium may potentially cause lethal oxidative stress. The inhibition of antioxidant activity in plasmodium may contribute to killing the malaria causing parasites.

General Function:
Udp-glycosyltransferase activity
Specific Function:
UDP-glucuronosyltransferases catalyze phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase water solubility and enhance excretion. They are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds (By similarity).

General Function:

Specific Function:
Represses expression from the ttgABC operon promoter and its own expression. Binds to a promoter region between the divergently transcribed ttgR and ttgABC genes/operons; in the presence of chloramphenicol or tetracycline this binding no longer occurs and ttgR and ttgABC are derepressed. This suggests that TtgR binds these antibiotics.
