Global regulator of sRNA function; host factor for RNA phage Q beta replication; HF-I; DNA- and RNA-binding protein; RNA chaperone; multiple regulatory roles: destabilzes ompA mRNA, improves rpoS translation, sRNA DsrA co-factor; binds RNAP; ATPase
|Function from GO|
See Help:Quickview for help with entering information in the Quickview table.
The C-terminal of Hfq is not necessary for hexamerization. RNA binding is located primarily at the N-terminal. Hfq has intrinsic ATPase activity (Sukhodolets, 2003; Arluison, 2007).
Hfq enhances RNA-RNA pairing.
