CC   -!- FUNCTION: RNA chaperone that binds small regulatory RNA (sRNAs) and
CC       mRNAs to facilitate mRNA translational regulation in response to
CC       envelope stress, environmental stress and changes in metabolite
CC       concentrations. Also binds with high specificity to tRNAs.
CC       {ECO:0000255|HAMAP-Rule:MF_00436}.
CC   -!- SUBUNIT: Homohexamer. {ECO:0000255|HAMAP-Rule:MF_00436}.
CC   -!- SIMILARITY: Belongs to the Hfq family. {ECO:0000255|HAMAP-
CC       Rule:MF_00436}.
