Hfq chaperone brings speed dating to bacterial sRNA

Sign Up to like & get
recommendations! Published in 2018 at "Wiley Interdisciplinary Reviews: RNA"

DOI: 10.1002/wrna.1475

Abstract: Hfq is a ubiquitous, Sm‐like RNA binding protein found in most bacteria and some archaea. Hfq binds small regulatory RNAs (sRNAs), facilitates base pairing between sRNAs and their mRNA targets, and directly binds and regulates… read more here.

DOI: 10.1016/j.molcel.2021.05.032

Abstract: Summary Polynucleotide phosphorylase (PNPase) is an ancient exoribonuclease conserved in the course of evolution and is found in species as diverse as bacteria and humans. Paradoxically, Escherichia coli PNPase can act not only as an… read more here.

DOI: 10.1063/5.0144604

Abstract: We adopt superconductor/ferromagnet/insulator/superconductor (SFIS) Josephson junctions (JJs) as both switching JJs and intrinsic π phase shifters in superconductor digital circuits. The critical current density (Jc) and characteristic voltage (Vc) of the SFIS junctions are about… read more here.

DOI: 10.1073/pnas.2208780119

Abstract: RNA-binding proteins contain intrinsically disordered regions whose functions in RNA recognition are poorly understood. The RNA chaperone Hfq is a homohexamer that contains six flexible C-terminal domains (CTDs). The effect of the CTDs on Hfq’s… read more here.

recommendations! Published in 2021 at "Nucleic Acids Research"

DOI: 10.1093/nar/gkab510

Abstract: Abstract In Pseudomonas aeruginosa the RNA chaperone Hfq and the catabolite repression control protein (Crc) govern translation of numerous transcripts during carbon catabolite repression. Here, Crc was shown to enhance Hfq-mediated translational repression of several… read more here.

DOI: 10.1111/1462-2920.13502

Abstract: Photorhabdus luminescens maintains a symbiotic relationship with the nematodes Heterorhabditis bacteriophora and together they infect and kill insect larvae. To maintain this symbiotic relationship, the bacteria must produce an array of secondary metabolites to assist… read more here.

recommendations! Published in 2018 at "Environmental Microbiology"

DOI: 10.1111/1462-2920.14263

Abstract: Metabolically versatile bacteria use catabolite repression control to select their preferred carbon sources, thus optimizing carbon metabolism. In pseudomonads, this occurs through the combined action of the proteins Hfq and Crc, which form stable tripartite… read more here.
