Using a Synechocystis sp. PCC 6803 mutant strain that lacks photosystem (PS) I and that synthesizes chlorophyll (Chl) b, a pigment that is not naturally present in the wild-type cyanobacterium, the functional consequences of incorporation of this pigment into the PS II core complex were investigated. Despite substitution of up to 75% of the Chl a in the PS II core complex by Chl b, the modified PS II centers remained essentially functional and were able to oxidize water and reduce Q(A), even… CONTINUE READING
