alpha-helix E of Spo0A is required for sigma(A)- but not for sigma(H)-dependent promoter activation in Bacillus subtilis [PDF]

open access: yes, 2004
At the onset of endospore formation in Bacillus subtilis, the DNA binding protein Spo0A activates transcription from two types of promoters. The first type includes the spoIIG and spoIIE promoters, which are used by sigma(A)-RNA polymerase, whereas the ...

Cinnamic‐Hydroxamic‐Acid Derivatives Exhibit Antibiotic, Anti‐Biofilm, and Supercoiling Relaxation Properties by Targeting Bacterial Nucleoid‐Associated Protein HU

open access: yesAdvanced Science, EarlyView.
Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.

The PDZ domain of the SpoIVB serine peptidase facilitates multiple functions [PDF]

open access: yes, 2001
During spore formation in Bacillus subtilis, the SpoIVB protein is a critical component of the sigma (K) regulatory checkpoint. SpoIVB has been shown to be a serine peptidase that is synthesized in the spore chamber and which self-cleaves, releasing ...

Receptors for chemotaxis in Bacillus subtilis [PDF]

open access: yesJournal of Bacteriology, 1975
At least three receptors for chemotaxis toward L-amino acids in Bacillus subtilis could be found with the aid of taxis competition experiments. They are called the asparagine receptor, which detects asparagine and glutamine, the isoleucine receptor, which detects isoleucine, leucine, valine, phenylalanine, serine, threonine, cysteine, and methionine ...

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

open access: yesAdvanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Universal Regulation of DNA Polymerase via Photocaged Primer Enables Light‐Start Isothermal Amplification on Demand

open access: yesAdvanced Science, EarlyView.
A simple and general photoactivatable approach is developed to regulate DNA polymerase activity, enabling light‐start isothermal amplification on demand. The molecular dynamics simulations reveals that the photocaged primer blocks DNA polymerase activity by inhibiting the conformational change of the polymerase.

Effect of Endophytic Microorganisms on Growth Rate of Crops

open access: yesТехника и технология пищевых производств
Increasing the yield of wheat, barley, and oats is a pressing issue. It largely depends on soil fertility. Mineral fertilizers, however, may be ineffective and unsustainable. As a result, microorganisms seem to be a promising alternative.

Evaluation of in situ valine production by Bacillus subtilis in young pigs

open access: yesAnimal, 2016
Mutants of Bacillus subtilis can be developed to overproduce Val in vitro. It was hypothesized that addition of Bacillus subtilis mutants to pig diets can be a strategy to supply the animal with Val.
