Sequence comparison and regulated expression of the norf1 gene. a Sequence comparison of Norf1 homologs from the two Synechocystis strains, Cyanothece ATCC 51142, 5 different strains of Crocosphaera encoding an identical protein and Anabaena (Nostoc) sp. PCC 7120. b Expression of norf1 in Synechocystis 6803 is strongly upregulated after transfer to darkness. c Bioluminescence of a Synechocystis 6803 reporter strain harboring a transcriptional fusion of Pnorf1 (−328 to +137, TSS at +1) and luxAB genes in response to transfer to darkness. Representative bioluminescence dataset indicating means ± SD of measurements for two biological replicates (= independent transformants). A strain carrying a promoterless luxAB was used as a negative control (measured in two independent cultures each)
