Cryo-em structure of a ca2+-bound photosynthetic lh1-rc complex containing multiple αβ-polypeptides

HIGHLIGHTS

• who: Kazutoshi Tani from the Mie University have published the research: Cryo-EM structure of a Ca2+-bound photosynthetic LH1-RC complex containing multiple αβ-polypeptides, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS of 28/06/2020
• what: The Trv. strain 970 RC structure from the study provides further insights into the structurefunction relationships of this unusual feature.

SUMMARY

The additional hydrogen_bond between His48 and BChl a, together with an interacting triangle formed with BChl a-Trp47-His48-BChl a, further strengthens interactions between the pigment and surrounding polypeptides and stabilizes the . . .
