Correction to: Communications Biology https://doi.org/10.1038/s42003-021-01878-9, published online 19 March 2021.
The original version of the Article contained an error in the second paragraph of the “Discussion” section. It was stated that “32 out of 39 microbial rhodopsins were found to have red-shifted absorption compared with the base wavelengths of each subfamily of microbial rhodopsins…”. However, after the publication, the authors became aware that the λmax of BacHR from Rubricoccus marinus (Accession: WP 094550238.1) was previously reported to be 542 nm1, which is close to the value determined in this study (541 nm).
The original version of the Article also contained an error in the fourth paragraph of the “Discussion” section. It was stated that “Four rhodopsins showed red-shifted absorption ≥20 nm than the base wavelength, three of which showed light-driven ion transport function.”. After publication, the authors become aware that ion transport activities of BacHRs from Rubricoccus marinus (Accession: WP 094550238.1) and Rubrivirga marina (Accession: WP 095509924.1) were also previously reported1.
