A Dual-Enzyme Amplification Loop for the Sensitive Biosensing of Endopeptidases
A rapid and sensitive approach for the detection of endopeptidases via a new analyte-triggered mutual emancipation of linker-immobilized enzymes (AMELIE) mechanism has been developed and demonstrated using a matrix metallopeptidase, a collagenase, as the

Genetic Evidence for Distinct Functions of Peptidoglycan Endopeptidases in Escherichia coli
Peptidoglycan (PG) is an essential component of the bacterial exoskeleton that plays a pivotal role in the maintenance of cell shape and resistance to cell lysis under high turgor pressures.

Highly active and selective endopeptidases with programmed substrate specificities [PDF]
A family of engineered endopeptidases has been created that is capable of cleaving a diverse array of peptide sequences with high selectivity and catalytic efficiency (kcat/KM > 104 M?1 s?1).

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Endopeptidase 24.16B. A new variant of endopeptidase 24.16.
A peptidase, isolated from rat testes, is inhibited by 1 mM o-phenanthroline, 1 microM N-(1-(R,S)-carboxyl-3-phenylpropyl)-Ala-Ala-Phe-p-aminobenzoate, and 6 mM Pro-Ile, properties similar to those ascribed to endopeptidase 24.16. The enzyme hydrolyzes dynorphin A-8, neurotensin 1-13, angiotensin I, and substance P.

Substrate‐Dependent Crosslinking by the Cytochrome P450 From Aminopyruvatide Biosynthesis
Substitutions in the aminopyruvatide precursor peptide altered the C─C linkage formed from a YLY motif by the P450 ApyO to a N─C linkage in a WLY motif. Moreover, constitutional isomers crosslinked by C─C and C─O linkages were formed from YYY or YWY motifs. ABSTRACT Cytochrome P450s catalyze an array of reactions including crosslinking of aromatic side

Two new cysteine endopeptidases obtained from the latex of Araujia hortorum fruits [PDF]
Two new endopeptidases were purified to homogeneity from the latex of Araujia hortorum fruits by a simple purification procedure involving ultracentrifugation and ion exchange chromatography.

Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.
