N2 - Background: Unicellular cyanobacteria separate photosynthesis and nitrogen fixation using a day-night cycle. Results: Cyanothece 51142 expresses a D1 protein exclusively in the dark period that assembles nonfunctional photosystem II. Conclusion: The unusual D1 is named sentinel D1 because it prevents photosynthesis from occurring during nitrogen fixation. Significance: Expression of sentinel D1 allows photosynthesis and nitrogen fixation to coexist in the cell.
