Viable but Nonculturable State, a Survival Strategy for Salmonella in Aquatic Environments

open access: yesWater and Environment Journal, EarlyView.
Transition of Salmonella from a culturable state to a viable but nonculturable state under various environmental stresses and current methods for detecting viable Salmonella in environmental samples. ABSTRACT In the relentless battle for survival, Salmonella has evolved mechanisms to withstand harsh conditions such as extreme temperatures, fluctuating ...

Segmentally Variable Genes: A New Perspective on Adaptation [PDF]

open access: yes, 2004
Genomic sequence variation is the hallmark of life and is key to understanding diversity and adaptation among the numerous microorganisms on earth. Analysis of the sequenced microbial genomes suggests that genes are evolving at many different rates.

Nutritional and Health Potential of Edible Seeds: Micronutrient Bioavailability and Mechanistic Insights

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
Their bioactive constituents act through antioxidant, anti‐inflammatory, and metabolic‐regulating mechanisms, validating their classification as functional foods. Evidence from clinical and biochemical studies largely supports these benefits, although some claims stem from preliminary or in vitro findings.

DNA gyrase could be a crucial regulatory factor for growth and survival of Mycobacterium leprae

open access: yesScientific Reports, 2019
Leprosy, an important infectious disease in humans caused by Mycobacterium leprae (Mle), remains endemic in many countries. Notably, the pathogen cannot be cultured in vitro, except in mouse footpads in vivo.

The latch modulates nucleotide and DNA binding to the helicase-like domain of Thermotoga maritima reverse gyrase and is required for positive DNA supercoiling [PDF]

open access: yes, 2017
Reverse gyrase is the only topoisomerase that can introduce positive supercoils into DNA in an ATP-dependent process. It has a modular structure and harnesses a helicase-like domain to support a topoisomerase activity, thereby creating the unique ...

Extensive structure‐activity relationship study of albicidin’s C‐terminal dipeptidic p‐aminobenzoic acid moiety [PDF]

open access: yes, 2019
Albicidin is a recently described natural product that strongly inhibits bacterial DNA gyrase. The pronounced activity, particularly against Gram‐negative bacteria, turns it into a promising lead structure for an antibacterial drug.

Mechanism of Inhibition of DNA Gyrase by ES‐1273, a Novel DNA Gyrase Inhibitor [PDF]

open access: yesMicrobiology and Immunology, 2007
AbstractWe investigated the mode of action of ES‐1273, a novel DNA gyrase inhibitor obtained by optimization of ES‐0615, which was found by screening our chemical library using anucleate cell blue assay. ES‐1273 exhibited the same antibacterial activity against S. aureus strains with amino acid change(s) conferring quinolone‐ and coumarin‐resistance as

Antibiotic Resistance, Biofilm Genes, and smeDEF Efflux Pump in Clinical Stenotrophomonas maltophilia Isolates From Iran

open access: yesMicrobiologyOpen, Volume 15, Issue 1, February 2026.
Iranian clinical Stenotrophomonas maltophilia isolates showed high susceptibility to trimethoprim/sulfamethoxazole, minocycline, and levofloxacin, but marked resistance to ceftazidime and ticarcillin‐clavulanate, alongside widespread biofilm production and resistance genes.

The Major Chromosome Condensation Factors Smc, HBsu, and Gyrase in Bacillus subtilis Operate via Strikingly Different Patterns of Motion

open access: yesmSphere, 2020
Although DNA-compacting proteins have been extensively characterized in vitro, knowledge of their DNA binding dynamics in vivo is greatly lacking.

Guiding strand passage: DNA-induced movement of the gyrase C-terminal domains defines an early step in the supercoiling cycle [PDF]

open access: yes, 2017
DNA gyrase catalyzes ATP-dependent negative supercoiling of DNA in a strand passage mechanism. A double-stranded segment of DNA, the T-segment, is passed through the gap in a transiently cleaved G-segment by coordinated closing and opening of three ...
