Role of APS reductase in biogeochemical sulfur isotope fractionation

Role of APS reductase in biogeochemical sulfur isotope fractionation, Published online: 09 January 2019; doi:10.1038/s41467-018-07878-4

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.
