Alignment of Yfr1 homologs and predicted secondary structure of Yfr1 from Nostoc sp. PCC 7120. (A) Alignment of sequences encoding Yfr1 homologs in 89 cyanobacterial genomes. The predicted transcript in Nostoc sp. PCC 7120 is shown in red. The described Yfr1 for Synechocystis sp. PCC 6803 (Mitschke et al., 2011a) is shown in blue. Genomes of heterocystous cyanobacteria are indicated with a black bar on the left side. (B) Predicted secondary structure of Yfr1 from Nostoc sp. PCC 7120. The sequence of a fully conserved motif is shown in yellow.
