a Top view from the stromal side showing the core subunits in ribbon style and PsaA1/A2, PsaB, and antenna proteins in surface representation. b Top view highlighting the antenna proteins in ribbon style and core subunits as surface. c Side view showing the transmembrane part. d Network of pigments and cofactors shown in stick and ball representations. CLAs are shown in green, XATs in purple, BCRs in blue, LRX in red, PQN in orange, lipids in light gray, iron-sulfur clusters in yellow-orange, and the iron cofactor in orange.
