Translational control of exported proteins in Escherichia coli [PDF]

Journal of Bacteriology, 1986
We recently described the suppression of export of a class of periplasmic proteins of Escherichia coli caused by overproduction of a C-terminal truncated periplasmic enzyme (GlpQ'). This truncated protein was not released into the periplasm but remained attached to the inner membrane and was accessible from the periplasm.

PhoU homologs from Staphylococcus aureus dimerization and protein interactions

Microbiology Spectrum
PhoU proteins are negative regulators of the phosphate response, regulate virulence, and contribute to antibiotic resistance. Staphylococcus aureus has multiple genes encoding PhoU homologs that regulate persister formation and potentially virulence, but

Expression and Purification of Mini G Proteins from Escherichia coli

Bio-Protocol, 2017
Heterotrimeric G proteins modulate intracellular signalling by transducing information from cell surface G protein-coupled receptors (GPCRs) to cytoplasmic effector proteins.

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

FEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Pathogenic Potential to Humans of Bovine Escherichia coli O26, Scotland [PDF]

, 2012
Escherichia coli O26 and O157 have similar overall prevalences in cattle in Scotland, but in humans, Shiga toxin–producing E. coli O26 infections are fewer and clinically less severe than E. coli O157 infections.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Global functional atlas of Escherichia coli encompassing previously uncharacterized proteins.

PLoS Biology, 2009
One-third of the 4,225 protein-coding genes of Escherichia coli K-12 remain functionally unannotated (orphans). Many map to distant clades such as Archaea, suggesting involvement in basic prokaryotic traits, whereas others appear restricted to E.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

FEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Structural insights into the dynamics and function of the C-terminus of the E. coli RNA chaperone Hfq [PDF]

, 2011
The hexameric Escherichia coli RNA chaperone Hfq (Hfq(Ec)) is involved in riboregulation of target mRNAs by small trans-encoded RNAs. Hfq proteins of different bacteria comprise an evolutionarily conserved core, whereas the C-terminus is variable in ...
