Characterization, Structure and Mechanism of Sulfide:quinone oxidoreductase (SQR) from Acidithiobacillus ferrooxidans
DownloadFall 2015
A key enzyme in maintaining sulfide homeostasis is the membrane-associated flavoenzyme sulfide:quinone oxidoreductase (SQR) found in nearly all domains of life (except plants). SQR maintains a critical equilibrium between sulfide (H2S, HS- and S2-) and elemental sulfur (S0), coupling the...

Complex II, or succinate dehydrogenase, is a vital component of aerobic life. Its function is critical for both the tricarboxylic acid cycle and the mitochondrial respiratory chain since it catalyzes the oxidation of succinate to fumarate, liberating two electrons that feed into the lipid-soluble...
