You are right. I have deleted this post!
Thanks!

Carotenoids enhance rhodopsin function as light-harvesting antennae and photocycle-accelerating pigments, a dual mechanism enhancing light energy capture and expanding microbial phototrophy.

The spectral properties of rhodopsins may shape depth distribution.
(Extra note) Carotenoid antennae seem unique to Flavobacteria PRs. These PRs may have evolved to rely on carotenoid binding. In other words, carotenoid-bound PR is their true native form.

3. The usable spectrum extends to shorter (blue) wavelengths, meaning these bacteria can still capture light near the bottom of the euphotic zone.
👉 In fact, expression was confirmed at greater depths!

2. H⁺-pumping rhodopsins (PR) with carotenoid antennae not only expand the usable wavelength range but also accelerate the photocycle!
👉 Shorter cycle = faster ion transport. Incredible!

1. Cl⁻-pumping rhodopsins (ClR) in marine Flavobacteria also use carotenoids as light-harvesting antennae!
👉 Previously thought to be limited to H⁺ pumps. And the binding mode is different—amazing!

Thanks!

Our paper reporting a new light-harvesting system in H⁺ & Cl⁻-pumping rhodopsins of marine bacteria is now out in Nature Microbiology! So excited!!!
Key discoveries (using isolated cultures from the research cruise Mirai MR10-01 — personally, this is super exciting🔥):
