Abstract

Read online

A light-harvesting chlorophyll-binding protein complex from an Antarctic green alga called Prasiola crispa can excite photosystem II with low energy far-red light. Here, through Cryo-EM analysis, the authors reveal its ring-shaped structure with 11-fold symmetry at 3.13 Å resolution.
