Redox Control of S-sulfocysteine Formation in Adenosine Phosphosulfate Reductase
Sulfur assimilation fuels bacterial growth by supplying the reduced sulfur required for the biosynthesis of sulfur-containing biomolecules. Adenosine 5'-phosphosulfate reductase (APSR) catalyzes the first reductive step of this pathway, converting adenosine 5'-phosphosulfate (APS) to adenosine monophosphate. This reaction proceeds through nucleophilic attack by catalytic C256, located in the…
