Aminopeptidase C of Aspergillus niger is a Novel Phenylalanine Aminopeptidase [PDF]

open access: yes, 2003
A novel enzyme with a specific phenylalanine aminopeptidase activity (ApsC) from Aspergillus niger (CBS 120.49) has been characterized. The derived amino acid sequence is not similar to any previously characterized aminopeptidase sequence but does share ...

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

open access: yesBiomolecules, 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 ...

Identification, by a monoclonal antibody, of a 53-kD protein associated with a tubulo-vesicular compartment at the cis-side of the Golgi apparatus [PDF]

open access: yes, 1988
Purified Golgi membranes of the human intestinal adenocarcinoma cell line Caco-2 were used as an antigen to produce a monoclonal antibody, G1/93, which specifically labels a tubulovesicular compartment near the cis side of the Golgi apparatus, including ...

Toxin release mediated by the novel autolysin Cwp19 in Clostridium difficile

open access: yesMicrobial 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

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

open access: yesMolecular 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.

Discovery and Engineering of Enzymes for Peptide Synthesis and Activation [PDF]

open access: yes, 2016
Enzymes are widely used for peptide synthesis, both for coupling and for terminal activation and modification. Broad-specificity proteases of different mechanistic classes can be used for C-terminal activation and peptide coupling reactions, whereas ...

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

open access: yeseLife
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.

Cathepsin E (EC 3.4.23.34) — a review

open access: yesFolia 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
