hfq homolog in C. sakazakii ATCC 29544. (A) Genomic organizations of hfq (KC866358), miaA (KC866359), and hflX (KJ577586) in C. sakazakii ATCC 29544. The promoter regions of hfq are indicated as P1 and P2. (B) Multiple-sequence alignment of hfq sequences in Gram-negative pathogens with a functionally identified hfq gene by Clustal Omega (version 1.2.1) and Genedoc. The uppercase letters in the consensus sequence indicate conserved amino acids appearing in all the aligned sequences, and the lowercase letters indicate conserved amino acids appearing in at least two sequences. Identical and conserved residues are in black and shaded gray (dark gray, >70% conserved; light gray, >40% conserved), respectively. Every 10 amino acids are indicated by asterisks.
