Expression of Brucella abortus Omp25 Protein in Lactococcus lactis Probiotic Bacteria [PDF]

Journal of Mazandaran University of Medical Sciences, 2023
Background and purpose: The sequence of Omp25 is conserved in all Brucella species. The high antigenicity of the product of this gene stimulates the host’s immune system. Using engineered probiotic bacteria is an appropriate method for vaccine transport.

The Ti Plasmid‐Encoded VirJ Functions as a Lysyl‐Phosphatidylglycerol Hydrolase in Agrobacterium tumefaciens

Molecular Microbiology, EarlyView.
We identify the long‐known virulence factor VirJ as a lysyl‐phosphatidylglycerol (L‐PG) hydrolase. Like the chromosomally encoded virulence factor AcvB, it prevents excessive accumulation of L‐PG in the membrane, thereby maintaining efficient T‐DNA transfer via the Type IV secretion system (T4SS) in Agrobacterium tumefaciens.

Evolutionary and Ecological Determinants of the Phenology of Births in Wild Large Herbivores, a Systematic Review

Mammal Review, Volume 56, Issue 2, June 2026.
This semi‐systematic review supports the two dominant drivers of birth phenology: the seasonality and predation hypotheses. Even though there is evidence of their importance, the effects of female, offspring and population characteristics remain marginally accounted for. Asian and South and Central American species are currently understudied.

Natural Products as the Modulators of Gut Microbiota: A Pool for the Development of New Treatment Against Obesity?

Food Frontiers, Volume 7, Issue 3, May 2026.
Natural compounds regulate gut microbiota by improving microbial balance and increasing probiotics, which boost short‐chain fatty acid production to alleviate insulin resistance and inflammation. Additionally, they stimulate appetite‐suppressing hormones through bile acid signaling, while inhibiting pathogenic bacteria to repair intestinal barrier ...

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1092-1103, May 2026.
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...
