In a recent paper inThe Journal of Biological Chemistry, researchers at Rutgers University and the University of California, San Diego have
shown that D1:1-PSII is not only more efficient at converting solar to chemical energy at very low light intensities compared to D1:2-PSII, but also grows faster. Their research shows that D1:1-PSII extends the lifetime of the transient chemical intermediates that form the charge separated state in the reaction center, the first “electrical battery” of photosynthesis.
