Correction to: Nature Communications https://doi.org/10.1038/s41467-020-18884-w, published online 19 October 2020.

The original version of this Article omitted a reference to previous work in “Li, M., Semchonok, D. A., Boekema, E. J. & Bruce, B. D. Characterization and evolution of tetrameric photosystem I from the thermophilic cyanobacterium Chroococcidiopsis sp TS-821. Plant Cell 26, 1230–1245 (2014)”. This has been added as reference 51 which has been added at the end of the fourth sentence of the third paragraph of the Discussion: “The short loop present … Chroococcidiopsis sp. TS-821 (PDBID: 6QWJ)51”.

The work in reference 50 was cited in the wrong location. It is now cited at the end of the previous sentence as reference 49: “The red loop we added to the Synechocystis WT PSI based on T. elongatus structure can also be found in Thermosynechococcus vulcanus46, Fischerella thermalis47 and Nostoc sp. PCC 712048,49”.

This has been corrected in the PDF and HTML versions of the Article.
