== Function ==
[https://www.uniprot.org/uniprot/HFQ_PSEA7 HFQ_PSEA7] RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs.
