Sulfide : quinone oxidoreductase (SQR) from the lugworm Arenicola marina shows cyanide- and thioredoxin-dependent activity.

The FEBS journal - 1 Mar 2008

Theissen Ursula, Martin William

Abstract excerpt

The lugworm Arenicola marina inhabits marine sediments in which sulfide concentrations can reach up to 2 mM. Although sulfide is a potent toxin for humans and most animals, because it inhibits mitochondrial cytochrome c oxidase at micromolar concentrations, A. marina can use electrons from sulfid...
