Cryo‐EM Analysis of a Tri‐Heme Cytochrome‐Associated RC‐LH1 Complex from the Marine Photoheterotrophic Bacterium Dinoroseobacter Shibae

open access: yesAdvanced Science, EarlyView.
Cryo‐EM reveals a closed 17‐subunit LH ring encircling the RC‐LH1 complex in Dinoroseobacter shibae, featuring a novel helix‐turn‐helix subunit bridging RC and LH. Mg2⁺/Ca2⁺ stabilizes the complex, while periplasmic Cyt c₂ mediates electron transfer via a tri‐heme Cyt to the special pair of bacteriochlorophylls. Insights into energy/electron efficiency
