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}.
