The three minor antennae of photosystem Ⅱ (PS Ⅱ), located between PS Ⅱ core complexes and the major light-harvesting chlorophyll (Chl) a/b complex (LHC Ⅱ), are important components for the structural and functional integrity of PS H supercomplexes.In this work, two types of PS Ⅱ preparations containing different antenna compositions, namely, 1) PS Ⅱ crude core complex (PS Ⅱ CC) containing all of the minor antennae and a small amount of major antennae and 2) purified PS Ⅱ dimeric core complexes (PS Ⅱ DC) without any Chl a/b proteins, were isolated from pea, and incorporated, together with LHC Ⅱ , into liposomes composed of thylakoid membrane lipids.
