Function and mechanism of action of the small regulatory RNA ArcZ in Enterobacterales

Alignments of mutated arcZ alleles in Enterobacterales. A BLASTN analysis was conducted on the enterobacterales NCBI RefSeq genomes using the conserved nucleotide sequence that contains the mutation (A) G to A or (B) G to U at position 90, in comparison with the Escherichia coli MG1655 reference genome. The mutation is indicated by a red arrow and surrounded by a red rectangle. Alignments were performed using MUSCLE (Edgar 2004) and processed with Jalview (Clamp et al. 2004).
