A Microorganism Transcriptional Regulation Algorithm Based on Generalized Regression Neural Network [PDF]

International Journal Bioautomation, 2019
Considering the importance of operon in microorganism transcriptional regulation, this paper sets up a new operon prediction model based on artificial neural network (ANN). Specifically, multiple genome information, ranging from intergenic distance (IGD),

Copper Chaperone CupA and Zinc Control CopY Regulation of the Pneumococcal cop Operon

mSphere, 2017
Any metal in excess can be toxic; therefore, metal homeostasis is critical to bacterial survival. Bacteria have developed specialized metal import and export systems for this purpose.

The role of the Staphylococcal VraTSR regulatory system on vancomycin resistance and vanA operon expression in vancomycin-resistant Staphylococcus aureus. [PDF]

PLoS ONE, 2014
Vancomycin is often the preferred treatment for invasive methicillin-resistant Staphylococcus aureus (MRSA) infection. With the increase in incidence of MRSA infections, the use of vancomycin has increased and, as feared, isolates of vancomycin-resistant

Photorhabdus lux-operon heat shock-like regulation

Heliyon, 2023
For decades, transcription of Photorhabdus luminescens lux-operon was considered being constitutive. Therefore, this lux-operon has been used for measurements in non-specific bacterial luminescent biosensors.

Gene Expression Analysis of Zobellia galactanivorans during the Degradation of Algal Polysaccharides Reveals both Substrate-Specific and Shared Transcriptome-Wide Responses

Frontiers in Microbiology, 2017
Flavobacteriia are recognized as key players in the marine carbon cycle, due to their ability to efficiently degrade algal polysaccharides both in the open ocean and in coastal regions.

Probable Role of Type IV Pili of Aeromonas hydrophila in Human Pathogenicity

Pathogens
Background: Aeromonas hydrophila is a widely recognized broad-spectrum pathogen that primarily targets the gastrointestinal tract. Type IV pili (T4P) are proteinaceous nano-machines located on the bacterial cell surface, playing a crucial role in host ...

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

Unraveling a Tangled Skein: Evolutionary Analysis of the Bacterial Gibberellin Biosynthetic Operon

mSphere, 2020
Gibberellin (GA) phytohormones are ubiquitous regulators of growth and developmental processes in vascular plants. The convergent evolution of GA production by plant-associated bacteria, including both symbiotic nitrogen-fixing rhizobia and ...

The Rhizobium etli trpB Gene Is Essential for an Effective Symbiotic Interaction with Phaseolus vulgaris

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.
