bacterial Hfq-like; Hfq, an abundant, ubiquitous RNA-binding protein, functions as a pleiotropic regulator of RNA metabolism in prokaryotes, required for transcription of some transcripts and degradation of others. Hfq binds small RNA molecules called riboregulators that modulate the stability or translation efficiency of RNA transcripts. Hfq binds preferentially to unstructured A/U-rich RNA sequences and is similar to the eukaryotic Sm proteins in both sequence and structure. Hfq forms a homo-hexameric ring similar to the heptameric ring of the Sm proteins. : Pssm-ID: 212463 Cd Length: 60 Bit Score: 82.19 E-value: 4.64e-23

RNA chaperone Hfq; This model represents the RNA-binding pleiotropic regulator Hfq, a small, Sm-like protein of bacteria. It helps pair regulatory noncoding RNAs with complementary mRNA target regions. It enhances the elongation of poly(A) tails on mRNA. It appears also to protect RNase E recognition sites (A/U-rich sequences with adjacent stem-loop structures) from cleavage. Being pleiotropic, it differs in some of its activities in different species. Hfq binds the non-coding regulatory RNA DsrA (see Rfam RF00014) in the few species known to have it: Escherichia coli, Shigella flexneri, Salmonella spp. In Azorhizobium caulinodans, an hfq mutant is unable to express nifA, and Hfq is called NrfA, for nif regulatory factor (see . The name hfq reflects phenomenology as a host factor for phage Q-beta RNA replication. [Regulatory functions, Other] Pssm-ID: 274101 Cd Length: 61 Bit Score: 75.44 E-value: 1.93e-20
