Structural Analyses on the Deamidation of N-Terminal Asn in the Human N-Degron Pathway

Biomolecules, 2020
The N-degron pathway is a proteolytic system in which a single N-terminal amino acid acts as a determinant of protein degradation. Especially, degradation signaling of N-terminal asparagine (Nt-Asn) in eukaryotes is initiated from its deamidation by N ...

Toxin release mediated by the novel autolysin Cwp19 in Clostridium difficile

Microbial Cell, 2018
Clostridium difficile, also known as Clostriodioides difficile, is a Gram positive, spore-forming bacterium and a leading cause of antibiotic-associated diarrhea in nosocomial environments. The key virulence factors of this pathogen are two toxins, toxin

Dimer-monomer transition defines a hyper-thermostable peptidoglycan hydrolase mined from bacterial proteome by lysin-derived antimicrobial peptide-primed screening

eLife
Phage-derived peptidoglycan hydrolases (i.e. lysins) are considered promising alternatives to conventional antibiotics due to their direct peptidoglycan degradation activity and low risk of resistance development.

Acyl peptide hydrolase degrades monomeric and oligomeric amyloid-beta peptide [PDF]

Molecular Neurodegeneration, 2009
Abstract Background The abnormal accumulation of amyloid-beta peptide is believed to cause malfunctioning of neurons in the Alzheimer's disease brain. Amyloid-beta exists in different assembly forms in the aging mammalian brain including monomers, oligomers, and aggregates, and in senile plaques, fibrils.

The plant Nudix hydrolase family. [PDF]

, 2008
Nudix hydrolases are a family of proteins defined by a conserved amino-acid sequence GX(5)-EX(7)REUXEEXGU, where U is a hydrophobic residue. These enzymes are widely distributed among all classes of organisms and catalyze, with varying degrees of ...

Cathepsin E (EC 3.4.23.34) — a review

Folia Histochemica et Cytobiologica, 2012
Cathepsin E belongs to the third class of enzymes — hydrolases, a subclass of peptide bond hydrolases and a sub-subclass of endopeptidases with aspartic catalytic sites. Cathepsin E is an endopeptidase with substrate specificity similar to that
