The peridinin-chlorophylla-protein (PCP) is one of the major light harvesting complexes (LHCs) in photosynthetic dinoflagellates. For this research, we analyzed the oligomeric state of PCP isolated from the dinoflagellateSymbiodinium, which has received increasing attention in recent years because of its role in coral bleaching. Size-exclusion chromatography (SEC) and small angle neutron scattering (SANS) analysis indicated PCP exists as monomers. Native mass spectrometry (native MS) demonstrated two oligomeric states of PCP, with the monomeric PCP being dominant. Lastly, the trimerization may not be necessary for PCP to function as a light-harvesting complex.
