Nature research paper: Phototrophy by antenna-containing rhodopsin pumps in aquatic environments
spheroplasts suspension expressing Kin4B8 or Kin4B8-G153F, respectively, with and without zeaxanthin. The spheroplasts were illuminated with violet , blue , or green light for 2 min . An enlarged plot of the first 15 s of illumination is displayed to the right of each measurement. The presented traces are the average of six or more independent biological replicates .
Extended Data Fig. 8 Diversity and distribution of PRs and XRs with and without fenestration among different prokaryotic phyla across four environments., Maximum likelihood phylogenetic analysis of the PR-XR-NQ clade based on representative protein sequences. Characterized ion pumps are indicated with dots, terminal branches are colored by the corresponding phylum. Major clades with more than one representative are highlighted and labeled. The tree is outgroup rooted.
rhodopsin, NQ – NQ sodium and chloride pumps, MACR – marine actinobacteria clade rhodopsins, PR – proteorhodopsins, TAT – TAT rhodopsins, XR – xanthorhodopsins, P1 – unnamed clade including QsActR, KrActR and related rhodopsins, P3 and P4 – currently unnamed clades.
