From: Architecture of symbiotic dinoflagellate photosystem I–light-harvesting supercomplex in Symbiodinium

a PSI–AcpPCI supercomplex viewed from stromal side. Core subunits are labeled as their names. LHCs are labeled as AcpPCI. Previously unidentified PSI core subunit is named as “PsaT”. b PSI–AcpPCI supercomplex viewed from lumenal side. Previously unidentified PSI core subunit is named as “PsaU”. c Side view of the PSI–LHC supercomplex. d AcpPCIs in PSI–LHC supercomplex. The long termini of AcpPCIs are indicated by arrows.
