The Minor Antenna Complexes in an Oxygen Evolving PSII Preparation
The PSII antenna system includes at least four different complexes containing both chlorophyll a and chlorophyll b. These are the main light-harvesting complex LHCII, which accounts for approx. 70% of the total chlorophyll of PSII, and the three minor complexes: CP24, CP26 and CP29. The LHCII component can be easily separated in a relatively pure form and it has been subjected to extensive investigation (1). The three minor components, which are listed above in order of increasing chlorophyll—a/chlorophyll—b ratio, are of more difficult purification and little is known on their functional role in PSII organization.
