Purification and Characterization of Two Phage PBSX-induced Lytic Enzymes of Bacillus subtilis 168: An N-Acetylmuramoyl-L-alanine Amidase and an N-Acetylmuramidase [PDF]

Microbiology, 1982
After heat-induction of the defective phage PBSX in a xhi-1479 mutant of Bacillus subtilis 168, the culture lysed rapidly even if the lyt-2 mutation was present (which greatly reduces the amount of the bacterial autolysins). Two lytic enzymes, an N-acetylmuramoyl-L-alanine amidase and an endo-N-acetylmuramidase, were purified from the culture ...

Purification, Characterization and Bactericidal Action of Lysozyme, Isolated from Bacillus subtillis BSN314: A Disintegrating Effect of Lysozyme on Gram-Positive and Gram-Negative Bacteria

Molecules, 2023
In the present study, lysozyme was purified by the following multi-step methodology: salt (ammonium sulfate) precipitation, dialysis, and ultrafiltration. The lysozyme potential was measured by enzymatic activity after each purification step.

Characterization of a FourU RNA Thermometer in the 5′ Untranslated Region of Autolysin Gene blyA in the Bacillus subtilis 168 Prophage SPβ

Biochemistry, 2023
RNA thermometers are noncoding RNA structures located in the 5′ untranslated regions (UTRs) of genes that regulate gene expression through temperature-dependent conformational changes.

Bacterial genes in the aphid genome: absence of functional gene transfer from Buchnera to its host. [PDF]

PLoS Genetics, 2010
Genome reduction is typical of obligate symbionts. In cellular organelles, this reduction partly reflects transfer of ancestral bacterial genes to the host genome, but little is known about gene transfer in other obligate symbioses.

Quantitative Support for the Metabolic Load Hypothesis: Metabolic Rate Measures Reveal Host‐Dependent Growth Costs in a Polyphagous Herbivore

Ecology and Evolution, Volume 15, Issue 12, December 2025.
The metabolic load hypothesis was tested in Polygonia c‐album caterpillars by comparing metabolic costs across three host plants. Larvae feeding on a chemically challenging host showed higher energy demands per unit of growth and reduced performance.

Mechanism study of alachlor biodegradation by Paecilomycesmarquandii with proteomic and metabolomic methods [PDF]

, 2015
Alachlor is an herbicide that is widely used worldwide to protect plant crops against broadleaf weedsand annual grasses. However, due to its endocrine-disrupting activity, its application had been bannedin the European Union.

Haemophilus ducreyi RpoE and CpxRA Appear To Play Distinct yet Complementary Roles in Regulation of Envelope-Related Functions [PDF]

, 2014
Haemophilus ducreyi causes the sexually transmitted disease chancroid and a chronic limb ulceration syndrome in children. In humans, H. ducreyi is found in an abscess and overcomes a hostile environment to establish infection.
