Inter-Protein Sequence Co-Evolution Predicts Known Physical Interactions in Bacterial Ribosomes and the Trp Operon. [PDF]

PLoS ONE, 2016
Interaction between proteins is a fundamental mechanism that underlies virtually all biological processes. Many important interactions are conserved across a large variety of species.

The Bacillus subtilis TRAP protein can induce transcription termination in the leader region of the tryptophan biosynthetic (trp) operon independent of the trp attenuator RNA. [PDF]

PLoS ONE, 2014
In Bacillus subtilis, transcription of the tryptophan biosynthetic operon is regulated by an attenuation mechanism. When intracellular tryptophan levels are high, the TRAP protein binds to the 5' leader region of the nascent trp mRNA and induces ...

ALE reveals a surprising link between [Fe-S] cluster formation, tryptophan biosynthesis and the potential regulatory protein TrpP in Corynebacterium glutamicum [PDF]

BMC Microbiology
Background The establishment of synthetic microbial communities comprising complementary auxotrophic strains requires efficient transport processes for common goods. With external supplementation of the required metabolite, most auxotrophic strains reach

<i>Xanthomonas campestris</i> utilizes IAA to regulate its viability and virulence by altering the production of BCAAs and ROS. [PDF]

mLife
Abstract Indole‐3‐acetic acid (IAA) is an important plant hormone that regulates a variety of physiological processes in plants, and it is also produced by some microbes. However, the biosynthesis and roles of IAA in microorganisms, particularly in plant pathogens, remain to be determined.

Isolation, identification, and plant growth-promoting mechanisms of strain BN5, with a focus on exogenously Trp-independent IAA biosynthesis, and its impact on cucumber cultivation [PDF]

Current Research in Microbial Sciences
The genus Niallia was recently separated as a taxonomic group from Bacillus based on conserved signature insertions and deletions in the genome. Unlike its role in bioremediation, its function in plant growth promotion has not attracted widespread ...

Dynamic interaction of the Yersinia pseudotuberculosis type three secretion system proteins LcrV and LcrG. [PDF]

Protein Sci
Abstract Yersinia pathogenicity is dependent on polarized translocation of effector proteins via the type III secretion system (T3SS). The tip complex situated on the needle structure of the T3SS is required for contact with the eukaryotic host membrane and is to an extent composed of pentameric LcrV. LcrV is a multifunctional protein that also acts as

Identification and Characterization of a Novel d-Branched-Chain Amino Acids Importer from Lactobacillus fermentum. [PDF]

Chembiochem
Certain lactic acid bacteria produce d‐branched‐chain amino acids (d‐BCAA) and encode isoleucine 2‐epimerase (ILEP) and an uncharacterized transporter (AAP). We demonstrate that the transporter is a novel, non‐stereospecific BCAA importer. The ILEP‐AAP operon likely aids in storing and utilizing BCAA in a form less accessible to other organisms ...

In silico approach for the identification of mirror repeats in selected operon genes of Escherichia coli strain K-12 substrain MG1655

Biomedical and Biotechnology Research Journal, 2022
Background: The repeating elements in the genes or genomes of living organisms are associated with a variety of functions at the molecular level. Mirror repeats (MRs) are unique type of repeat sequences among them, which are found to be linked with H-DNA
