Figure 1From: A motif-based search in bacterial genomes identifies the ortholog of the small RNA Yfr1 in all lineages of cyanobacteriaComparison of putative Yfr1 RNAs from 15 different Prochlorococcus and Synechococcus. A. Sequence alignment of the top scoring sequences obtained by BlastN using the known Yfr1 sequences [7] as a query. The respective strain numbers are prefixed "Pro" and "Syn" for Prochlorococcus and Synechococcus. B. Sequence/structure model for putative Yfr1 RNAs from 15 different Prochlorococcus and Synechococcus as shown in part A. Sequence is given in IUPAC-notation (R: A or G; Y: C or U; S: G or C; K: G or U; B: G, U or C; V: G, C or A; D: G, U or A; H: A, C or U). Base pair colors indicate the number of different base pairs which occur in the different sequences at this position (red = 1, yellow = 2, green = 3) and their shading resembles the frequency of base pairing, i.e. the number of sequences where this base pair is not present.Back to article page
