Changes in S-isotope ratios over time provide clues to understanding the co-evolution of Earth and its biosphere. Here the authors determine the isotope effect of the first reductive enzyme in the sulfate respiration pathway and reinterpret sedimentary S-isotope records based on this biochemical constraint.
