Characterization of a Nanovaccine Platform Based on an α1,2-Mannobiose Derivative Shows Species-non-specific Targeting to Human, Bovine, Mouse, and Teleost Fish Dendritic Cells.

Dendritic cells serve as the main immune cells that trigger the immune response. We developed a simple and cost-effective nanovaccine platform based on the α1',2-mannobiose derivative for dendritic cell targeting. In previous work, we have formulated the α1,2-mannobiose-based nanovaccine platform with plasmid DNA and tested it in cattle against BoHV-1 infection.

Archaeal JAB1/MPN/MOV34 metalloenzyme (HvJAMM1) cleaves ubiquitin-like small archaeal modifier proteins (SAMPs) from protein-conjugates.

Proteins with JAB1/MPN/MOV34 metalloenzyme (JAMM/MPN+) domains are widespread among all domains of life, yet poorly understood. Here we report the purification and characterization of an archaeal JAMM/MPN+ domain protein (HvJAMM1) from Haloferax volcanii that cleaves ubiquitin-like small archaeal modifier proteins (SAMP1/2) from protein conjugates. HvJAMM1 cleaved SAMP1/2 conjugates generated in H.
