International audience; To adapt to changing environments, bacteria have evolved numerous pathways that activate stress response genes. In Gram-positive bacteria, the stressosome, a cytoplasmic complex, relays external cues and activates the sigma B

In most organisms, heme biosynthesis is strictly controlled so as to avoid heme and heme precursor accumulation, which is toxic. Escherichia coli regulates heme biosynthesis by a feedback loop involving heme-induced proteolytic cleavage of HemA, glut

Sequestration of a two-component response regulator by a riboswitch-regulated noncoding RNA

Publikováno v: Science. 345:940-943

A dual-action RNA switch for expression Riboswitches are short segments of RNA that bind small molecules and switch between two different conformations, thereby regulating gene expression (see the Perspective by Chen and Gottesman). DebRoy et al. and

How bacteria switch between tracks Bacterial riboswitches prevent the formation of full-length messenger RNA, and hence proteins, via transcriptional termination in response to metabolites. However, identifying riboswitches within the genome has prev

Role of Hfq in iron-dependent and -independent gene regulation in Neisseria meningitidis

Autor: Caroline A. Genco, Björn M. Reinhard, J. R. Mellin, Delia Lopez, Olivia Green, Ryan McClure

Publikováno v: Microbiology

In Neisseria meningitidis, iron-responsive gene regulation is mediated primarily by the ferric uptake regulator (Fur) protein. When complexed with iron, Fur represses gene expression by preventing transcription initiation. Fur can also indirectly act

Publikováno v: Proceedings of the National Academy of Sciences of the United States of America. 110(32)

Riboswitches are ligand-binding elements located in 5′ untranslated regions of messenger RNAs, which regulate expression of downstream genes. In Listeria monocytogenes , a vitamin B 12 -binding (B 12 ) riboswitch was identified, not upstream of a g
