An NMR Study on the clpC Operon Binding Region of Transcription Factor CtsR from Bacillus subtilis
Chinese Journal of Magnetic Resonance, 2021 When Gram-positive bacterium Bacillus subtilis responds to heat-shock, protein arginine kinase McsB phosphorylates Arg62 (R) in the clpC operon binding region of transcription factor CtsR, leading to dissociation of CtsR and clpC operon and initiation of

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.

Development of an sRNA-mediated conditional knockdown system for Chlamydia trachomatis
mBioWe describe a new Chlamydia trachomatis protein depletion method that uses an engineered small RNA (sRNA) to inhibit translation of a target gene. In proof-of-principle experiments, we induced functional knockdown of IncA, a fusion-mediating inclusion ...

Molecular Plant-Microbe Interactions, 1999 A mutant strain (CTNUX4) of Rhizobium etli carrying Tn5 unable to grow with ammonium as the sole nitrogen source was isolated and characterized. Sequence analysis showed that Tn5 is inserted into a trpB (tryptophan synthase)-homologous gene.

Operon and non-operon gene clusters in the C. elegans genome [PDF]
WormBook, 2014 Nearly 15% of the ~20,000 C. elegans genes are contained in operons, multigene clusters controlled by a single promoter. The vast majority of these are of a type where the genes in the cluster are ~100 bp apart and the pre-mRNA is processed by 3' end formation accompanied by trans-splicing.

FEBS Open Bio, EarlyView.The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.

BMC Genomics, 2009 Background The repABC plasmid family, which is extensively present within Alphaproteobacteria, and some secondary chromosomes of the Rhizobiales have the particular feature that all the elements involved in replication and partitioning reside within one ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum
FEBS Open Bio, EarlyView.Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Angewandte Chemie, EarlyView.A synthetic biology platform was established for the complete refactoring of complex anthracycline biosynthetic pathways in Streptomyces coelicolor using standardized, chemically synthetic DNA parts. This modular construction enabled streamlined combinatorial biosynthesis, yielding novel analogs that decouple DNA damage from chromatin damage (histone ...
