  • Microbiology and Molecular Biology Reviews
  • 1 March 2002
SUMMARY α-Crystallins were originally recognized as proteins contributing to the transparency of the mammalian eye lens. Subsequently, they have been found in many, but not all, members of theExpand

  • 1 January 1999
The expression of eubacterial heat shock genes is efficiently controlled at the transcriptional level by both positive and negative mechanisms. Positive control operates by the use of alternativeExpand

Bacterial RNA thermometers: molecular zippers and switches
Bacteria use complex strategies to coordinate temperature-dependent gene expression. Many genes encoding heat shock proteins and virulence factors are regulated by temperature-sensing RNA sequences,Expand

Concerted Actions of a Thermo-labile Regulator and a Unique Intergenic RNA Thermosensor Control Yersinia Virulence
Expression of all Yersinia pathogenicity factors encoded on the virulence plasmid, including the yop effector and the ysc type III secretion genes, is controlled by the transcriptional activator LcrFExpand

Small RNA‐mediated control of the Agrobacterium tumefaciens GABA binding protein
Wounded plants activate a complex defence programme in response to Agrobacterium tumefaciens. They synthesize the non‐proteinogenic amino acid γ‐aminobutyric acid (GABA), which stimulates degradationExpand

Structure and function of the bacterial AAA protease FtsH.
Proteolysis of regulatory proteins or key enzymes of biosynthetic pathways is a universal mechanism to rapidly adjust the cellular proteome to particular environmental needs. Among the fiveExpand

Multiple small heat shock proteins in rhizobia.
Seven genes coding for small heat shock proteins (sHsps) in Bradyrhizobium japonicum have been identified. They are organized in five operons that are coordinately regulated by ROSE, a negativelyExpand

The C‐terminal end of LpxC is required for degradation by the FtsH protease
Lipopolysaccharide (LPS) biosynthesis is essential in Gram negative bacteria. LpxC, the key enzyme in LPS formation, catalyses the limiting reaction and controls the ratio between LPS andExpand

FourU: a novel type of RNA thermometer in Salmonella
The translation of many heat shock and virulence genes is controlled by RNA thermometers. Usually, they are located in the 5′‐untranslated region (5′‐UTR) and block the Shine‐Dalgarno (SD) sequenceExpand

Molecular basis for temperature sensing by an RNA thermometer
Regulatory RNA elements, like riboswitches, respond to intracellular signals by three‐dimensional (3D) conformational changes. RNA thermometers employ a similar strategy to sense temperature changesExpand
