Strain variation in ppGpp concentration and RpoS levels in laboratory strains of Escherichia coli K-12
(SOC GENERAL MICROBIOLOGY, 2008)
Laboratory strains and natural isolates of Escherichia coli differ in their level of stress resistance due to strain variation in the level of the sigma factor sigma(S) (or RpoS), the transcriptional master controller of ...
How the initiating ribosome copes with ppGpp to translate mRNAs
(Public Library of Science, 2020-01-01)
During host colonization, bacteria use the alarmones (p)ppGpp to reshape their proteome by acting pleiotropically on DNA, RNA, and protein synthesis. Here, we elucidate how the initiating ribosome senses the cellular pool ...

New insights into the regulatory mechanisms of ppGpp and DksA on Escherichia coli RNA polymerase-promoter complex
(Oxford University Press, 2015)
The stringent response modulators, guanosine tetraphosphate (ppGpp) and protein DksA, bind RNA polymerase (RNAP) and regulate gene expression to adapt bacteria to different environmental conditions. Here, we use Atomic ...
Nucleotide second messenger-based signaling in extreme acidophiles of the Acidithiobacillus species complex: Partition between the core and variable gene complements
(Frontiers Media, 2019)
Cyclic and linear nucleotides are key elements of the signal transduction networks linking perception of the environment to specific cellular behavior of prokaryotes. These molecular mechanisms are particularly important ...
Stand-level patterns of carbon fluxes and partitioning in a Eucalyptus grandis plantation across a gradient of productivity, in Sao Paulo State, Brazil
(OXFORD UNIV PRESSOXFORD, 2012)
Wood production represents a large but variable fraction of gross primary production (GPP) in highly productive Eucalyptus plantations. Assessing patterns of carbon (C) partitioning (C flux as a fraction of GPP) between ...
Arquitectura funcional para la implementación de mobile IPTV sobre redes LTE y LTE-Avanced
(Universidad Santo Tomás. Seccional Bucaramanga, 2011-12-07)
The stringent response plays a key role in Bacillus subtilis survival of fatty acid starvation
(Wiley Blackwell Publishing, Inc, 2017-02)
The stringent response is a universal adaptive mechanism to protect bacteria from nutritional and environmental stresses. The role of the stringent response during lipid starvation has been studied only in Gram-negative ...
