Structures of a phycobilisome in light-harvesting and photoprotected states
Cryogenic electron microscopy structures of the Synechocystis phycobilisome—alone and bound with orange carotenoid protein—reveal detailed information regarding the biophysical basis of the control of cyanobacterial light harvesting.

Structural basis of energy transfer in Porphyridium purpureum phycobilisome
The cryo-electron microscopy structure of a phycobilisome from the red alga Porphyridium purpureum reveals how aromatic interactions between the linker proteins and the chromophores drive a unidirectional transfer of energy.

Cryo-EM structure of the
Blastochloris viridis LH1–RC complex at 2.9 Å
A cryo-electron microscopy structure of the light-harvesting–reaction centre (LH1–RC) complex of the photosynthetic bacterium Blastochloris viridis suggests factors that underlie the large redshift in the absorption spectrum of bacteriochlorophyll in the complex and that promote quinone–quinol translocation across the LH1 ring.

Structure of phycobilisome from the red alga Griffithsia pacifica
Single-particle cryo-electron microscopy is used to resolve the structure of the phycobilisome, a 16.8-megadalton light-harvesting megacomplex, from the red alga Griffithsia pacifica at a resolution of 3.5 Å.
