adenylyl-sulfate reductase  M-CSA #123

Adenylylsulfate (adenosine 5'-phosphosulfate) reductase (APS reductase) from Archaeoglobus fulgidus catalyses the reversible reduction of APS to sulfite and AMP. This pathway provides sulfate which serves as a terminal electron acceptor of an anaerobic respiratory electron transfer chain. Electrons are also provided for anoxygenic photosynthesis and denitrification.
