Notes:
Two open reading frames (slr0115 and slr0947) in the genome of the cyanobacterium Synechocystis sp. PCC 6803 are shown to be involved in the regulation of the coupling of phycobilisomes to photosynthetic reaction centres. Homologues of these genes, called ycf27, have been found in a range of phycobilin-containing organisms. The slr0115 and slr0947 gene products are OmpR-type DNA-binding response regulator proteins. Deletion of slr0115 results in increased efficiency of energy transfer from phycobilisomes to photosystem II relative to photosystem I. Reduction of the copy number of slr0947 has the opposite phenotypic effect. We have given the slr0115 and slr0947 genes the designations rpaA and rpaB respectively.
